+#         PWC 60 TASK #1 › Excel Column
+#         Reviewed by: Ryan Thompson
+#             Write a script that accepts a number and returns the Excel Column
+#             Name it represents and vice-versa.
+#
+#             Excel columns start at A and increase lexicographically using the 26
+#             letters of the English alphabet, A..Z. After Z, the columns pick up
+#             an extra “digit”, going from AA, AB, etc., which could (in theory)
+#             continue to an arbitrary number of digits. In practice, Excel sheets
+#             are limited to 16,384 columns.
+#
+#             Example
+#
+#             Input Number: 28 Output: AB
+#
+#             Input Column Name: AD Output: 30
+#
+#         METHOD
+#
+#             So it’s base 26, using capital letters for the symbols. Cool.
+#
+#             Ok, well, sort of. Turns out it’s a little different, a little
+#             more complicated than that.
+#
+#             “How so?” you say. Glad you asked. It seems we have a little
+#             problem with Z.
+#
+#             “Z?” you say. Yes, Z.
+#
+#             As usual, the first order of business is to unpack the challenge
+#             and nail down a few outstanding questions. Then the problem will
+#             make a little more sense.
+#
+#             All we are told in the text about Excel is that the column
+#             identifiers start with A and continue through Z, then recommence
+#             labelling with AA to AZ, etcetera. In order for the mapping 28 →
+#             AB to occur, 27 maps to AA, and what’s left is A-Z mapping to 1 to
+#             26. So the indexing starts at 1. Fair enough.
+#
+#             The cycle is undoubtably 26; converting to base 26 seems a
+#             reasonable start. We can then substitute the letters A-Z for the
+#             normal representation 0-9 followed by A-P. The problems start
+#             immediately, with the number 1026, or if you look at it another
+#             way, 0.
+#
+#             To make visualization a little easier it might make sense to
+#             relate to base 10, our standard counting system. To count in base
+#             10, we use the 10 digits 0 through 9, then we start to
+#             positionally combine these digits to make the numbers 10, 11, and
+#             so on. So if we choose to use letters for our digits, do we map
+#             the letters to 0-9 or 1-10? In either case we are confounded by
+#             10, being the last member of the mapping, but being composed of
+#             two digits in the number system.
+#
+#             But back to base 26 and Z, if we use the tried and true method of
+#             dividing out the base, we’ll never get a remainder of 26, but
+#             rather 0. So do we make 0 → Z ? Then 26 → AZ, which is wrong. Z
+#             has to be 26, because the next number, 27 is AA (think 11 here if
+#             you must, the association is correct) Similarly, fudging our
+#             numbers by 1 in other ways, either reducing the input or the
+#             remainder to match 0 indexing fails as well, either starting on
+#             the wrong letter or erring at the transition to two digits.
+#             Sometimes we start at B, or later we get BA instead of AA. There’s
+#             a lot of ways down this mountain, I assure you. We are being
+#             confounded by the fact that our counting is indexed to 1 and our
+#             base is indexed to 0.
+#
+#             The solution is to shift the input number to a 0-based lookup
+#             within the dividing out itself, by subtracting 1 from the number
+#             during the computation of the remainder. Then 26 becomes 25 and
+#             the arithmetic all works out; 27 follows 26 as it should be and AA
+#             follows Z. This gives us the correct translation, finally. Mixing
+#             indexing systems is always a red flag for danger, and adding in
+#             modular arithmetic to the mix just adds to the confusion.
+#
+#             To do the conversion from Excel to decimal is a little less
+#             complicated, fortunately for us. To run the dividing out in
+#             reverse we first need to establish a lookup mapping the letters
+#             A-Z to 1-26, and then we progress through the string taking off
+#             letters from the right and summing the product of the lookup value
+#             and 26 to the power of the (0-based) position for each place. In
+#             base-10, this multiplier is 1, 10, 100 and so on. In base-26 we
+#             use 26^0, 26^1, 26^2… To implement this, we dice the string into
+#             an array of chars, reverse() the array and shift() from the left.
+#             Then we can keep track of the loops, counting from 0, to get the
+#             appropriate power.

+#         Find Numbers
+#         Challenge by: Ryan Thompson
+#             Write a script that accepts list of positive numbers (@L) and two
+#             positive numbers $X and $Y.
+#
+#             The script should print all possible numbers made by concatenating
+#             the numbers from @L, whose length is exactly $X but value is less
+#             than $Y.
+#
+#             Example
+#                 Input:
+#
+#                     @L = (0, 1, 2, 5);
+#                     $X = 2;
+#                     $Y = 21;
+#
+#                 Output:
+#
+#                     10, 11, 12, 15, 20
+#
+#         METHOD
+#
+#             This is another example of what I call concrete number theory, where
+#             we conflate the ideas of numbers and the symbols used to represent
+#             them. We’re going to assemble digits positionally rather than
+#             mathematically, and then evaluate those resultant numbers according
+#             to some criteria. In this case the number of positions is equal to
+#             an input x, and the resultant number is less than an input y.
+#
+#             To manufacture the number, we’re going to combine elements from an
+#             input array. Considering the choices as sets, we are looking for
+#             permutations of combinations with repetitions of length k elements
+#             from set n. This is known in Set Theory as
+#
+#                     k-element variations of n-elements with repetition
+#
+#
+#             as distinguished from variations without repetition. For a list of n
+#             elements we have
+#
+#                     VR(n,k) = n^k
+#
+#             variations; because every position can contain every element at any
+#             time, so the product is
+#
+#                     n × n × n …
+#
+#             for as many positions as required. There is one small caveat to
+#             this, however, and that is the number 0.
+#
+#             Despite the given specification given a list of positive numbers,
+#             zero is neither positive nor negative, so does not belong according
+#             to that rule. However the example list explicitly includes it, so we
+#             will follow suit and allow it, despite the specification. Sometimes
+#             we must figure out that what the customer wants is not exactly what
+#             they asked for.
+#
+#             To create our master list of variations, we’ll create a list, and
+#             then iterate through the elements one at a time, adding an new value
+#             and creating a new set of variations for every option. Bu carefully
+#             keeping track of indexes we can just keep just one list as a queue,
+#             shifting elements off the front and adding new variations on the
+#             end. As we allow repetition, it makes no sense to duplicate elements
+#             in the input; it’s a set, not an ordered list. Thus if the number 2
+#             is an element, if 2 is repeated later in the input it still can be
+#             present in any position, so it makes no difference. We’ll allow it,
+#             because you can’t control people, but roll our eyes a bit and filter
+#             out duplicates. Also, it we sort our list before we start, the
+#             results will come out sorted, which is nice.
+#
+#             We will use our now sorted and filtered list to start our list of
+#             variations. At this point, the first digit of the final number, we
+#             will need to address 0 again, because earlier we specifically
+#             allowed it. The problem is if we have a leading zero on a number, it
+#             will not, by convention, be considered in the final construction,
+#             and as such will shorten the positional count of the result,
+#             violating that criterium. As far as convention goes, in case there
+#             was any question remaining whether leading zeros are allowed
+#             (because I can certainly see a case for it) we refer again to the
+#             text. The example given in the challenge does not include the
+#             results 00, 01, 02, or 05. Ok, so that’s a no-no, and we must for
+#             the initial value exclude 0 if it is present. After this it’s fine,
+#             as it won’t affect position. So we will need to selectively filter
+#             it out only for the initialization. We can either check the value at
+#             index 0, because the list is positive and sorted, then remove it if
+#             present, or grep the sorted array on the values themselves, which
+#             will fail on 0. Kind of a high-pass filter.
+#
+#             But before we’re done there also exists a singular pathological case
+#             to handle where x = 1 and the list includes 0. If we are not
+#             allowing leading 0s, does a solitary 0 count as a valid answer?
+#             Sure, it’s not a leading zero if it’s the only value present, even
+#             if that value is the absence of value. Really this relates back to
+#             the acceptance of 0 as a valid number at all, which is a much more
+#             recent, non-obvious and complicated development than many people
+#             understand, and entirely worthy of a discussion unto itself*. In
+#             another way it reminds me of pluralizing cats: no cats, 1 cat, 2
+#             cats. The progression is unexpectedly complex. So we eliminate the
+#             leading 0 of the first result set, but need to add it back in one
+#             case, when x = 1.

+#             To do the conversion from Excel to decimal is a little less
+#             complicated, fortunately for us. To run the dividing out in
+#             reverse we first need to establish a lookup mapping the letters
+#             A-Z to 1-26, and then we progress through the string taking off
+#             letters from the right and summing the product of the lookup value
+#             and 26 to the power of the (0-based) position for each place. In
+#             base-10, this multiplier is 1, 10, 100 and so on. In base-26 we
+#             use 26^0, 26^1, 26^2… To implement this, we dice the string into
+#             an array of chars, reverse() the array and shift() from the left.
+#             Then we can keep track of the loops, counting from 0, to get the
+#             appropriate power.

+#         PWC 60 TASK #2
+#         Find Numbers
+#         Challenge by: Ryan Thompson
+#             Write a script that accepts list of positive numbers (@L) and two
+#             positive numbers $X and $Y.
+#
+#             The script should print all possible numbers made by concatenating
+#             the numbers from @L, whose length is exactly $X but value is less
+#             than $Y.
+#
+#             Example
+#                 Input:
+#
+#                     @L = (0, 1, 2, 5);
+#                     $X = 2;
+#                     $Y = 21;
+#
+#                 Output:
+#
+#                     10, 11, 12, 15, 20
+#
+#         METHOD
+#
+#             This is another example of what I call concrete number theory, where
+#             we conflate the ideas of numbers and the symbols used to represent
+#             them. We’re going to assemble digits positionally rather than
+#             mathematically, and then evaluate those resultant numbers according
+#             to some criteria. In this case the number of positions is equal to
+#             an input x, and the resultant number is less than an input y.
+#
+#             To manufacture the number, we’re going to combine elements from an
+#             input array. Considering the choices as sets, we are looking for
+#             permutations of combinations with repetitions of length k elements
+#             from set n. This is known in Set Theory as
+#
+#                     k-element variations of n-elements with repetition
+#
+#
+#             as distinguished from variations without repetition. For a list of n
+#             elements we have
+#
+#                     VR(n,k) = n^k
+#
+#             variations; because every position can contain every element at any
+#             time, so the product is
+#
+#                     n × n × n …
+#
+#             for as many positions as required. There is one small caveat to
+#             this, however, and that is the number 0.
+#
+#             Despite the given specification given a list of positive numbers,
+#             zero is neither positive nor negative, so does not belong according
+#             to that rule. However the example list explicitly includes it, so we
+#             will follow suit and allow it, despite the specification. Sometimes
+#             we must figure out that what the customer wants is not exactly what
+#             they asked for.
+#
+#             To create our master list of variations, we’ll create a list, and
+#             then iterate through the elements one at a time, adding an new value
+#             and creating a new set of variations for every option. Bu carefully
+#             keeping track of indexes we can just keep just one list as a queue,
+#             shifting elements off the front and adding new variations on the
+#             end. As we allow repetition, it makes no sense to duplicate elements
+#             in the input; it’s a set, not an ordered list. Thus if the number 2
+#             is an element, if 2 is repeated later in the input it still can be
+#             present in any position, so it makes no difference. We’ll allow it,
+#             because you can’t control people, but roll our eyes a bit and filter
+#             out duplicates. Also, it we sort our list before we start, the
+#             results will come out sorted, which is nice.
+#
+#             We will use our now sorted and filtered list to start our list of
+#             variations. At this point, the first digit of the final number, we
+#             will need to address 0 again, because earlier we specifically
+#             allowed it. The problem is if we have a leading zero on a number, it
+#             will not, by convention, be considered in the final construction,
+#             and as such will shorten the positional count of the result,
+#             violating that criterium. As far as convention goes, in case there
+#             was any question remaining whether leading zeros are allowed
+#             (because I can certainly see a case for it) we refer again to the
+#             text. The example given in the challenge does not include the
+#             results 00, 01, 02, or 05. Ok, so that’s a no-no, and we must for
+#             the initial value exclude 0 if it is present. After this it’s fine,
+#             as it won’t affect position. So we will need to selectively filter
+#             it out only for the initialization. We can either check the value at
+#             index 0, because the list is positive and sorted, then remove it if
+#             present, or grep the sorted array on the values themselves, which
+#             will fail on 0. Kind of a high-pass filter.
+#
+#             But before we’re done there also exists a singular pathological case
+#             to handle where x = 1 and the list includes 0. If we are not
+#             allowing leading 0s, does a solitary 0 count as a valid answer?
+#             Sure, it’s not a leading zero if it’s the only value present, even
+#             if that value is the absence of value. Really this relates back to
+#             the acceptance of 0 as a valid number at all, which is a much more
+#             recent, non-obvious and complicated development than many people
+#             understand, and entirely worthy of a discussion unto itself*. In
+#             another way it reminds me of pluralizing cats: no cats, 1 cat, 2
+#             cats. The progression is unexpectedly complex. So we eliminate the
+#             leading 0 of the first result set, but need to add it back in one
+#             case, when x = 1.
