+## [Challenge 1](https://perlweeklychallenge.org/blog/perl-weekly-challenge-004/#challenge-1)
+
+Write a script to output the same number of PI digits as the size
+of your script. Say, if your script size is `10`, it should print
+`3.141592653`.
+
+### Solutions
+
+
+## [Challenge 2](https://perlweeklychallenge.org/blog/perl-weekly-challenge-004/#challenge-2)
+
+You are given a file containing a list of words (case insensitive
+1 word per line) and a list of letters. Print each word from the
+file that can be made using only letters from the list. You can use
+each letter only once (though there can be duplicates and you can
+use each of them once), you don't have to use all the letters.
+(Disclaimer: The challenge was proposed by Scimon Proctor)

Subject: Rewrite of the Perl solution

This solution can be run direction, not requiring any options
(the previous solution required an undocumented -M5.010 option).
Instead of using atan2(), we now use a base-60 encoded list
of digts of pi (after the decimal dot).

The source code is 1485 characters, including white space.
The output is 1487 characters, of which 1485 digits (the others
are a decimal dot, and a new line).

@@ -6,6 +6,20 @@ Write a script to output the same number of PI digits as the size
 of your script. Say, if your script size is `10`, it should print
 `3.141592653`.
 
+### Notes
+We're going to encode the digits (after the decimal dot) in groups
+of 9 in base-91. 9 base-10 digits need 5 base-91 digits. We represent
+the base-91 digits as ASCII characters, from '#' (0) to '~' (90).
+Now, '#' to '~' covers a range of 92; however, when encoding, we
+will be skipping '\'. Choosing a range from '#' to '~' while skipping
+'\' means we can easily use this in double quoted strings (for languages
+which don't do interpolation).
+
+This gives a reduction of 44% (9 decimals encoded in 5 characters). By 
+using 3242 digits of Pi, we decidate 1800 characters to the encoding
+of Pi, which gives us plenty of room to write code to do the decoding
+and printing. We may even need to filler comments to make it all work out.
