+Task 1: Sorted Matrix
+
+You are given a n x n matrix where n >= 2.
+Write a script to find 3rd smallest element in the sorted matrix.
+
+Example 1
+
+  Input: @matrix =  [3, 1, 2], [5, 2, 4], [0, 1, 3]
+  Output: 1
+
+  The sorted list of the given matrix: 0, 1, 1, 2, 2, 3, 3, 4, 5.
+  The 3rd smallest of the sorted list is 1.
+
+Example 2
+
+  Input: @matrix = ([2, 1], [4, 5])
+  Output: 4
+
+  The sorted list of the given matrix: 1, 2, 4, 5.
+  The 3rd smallest of the sorted list is 4.
+
+Example 3
+
+  Input: @matrix = ([1, 0, 3], [0, 0, 0], [1, 2, 1])
+  Output: 0
+
+  The sorted list of the given matrix: 0, 0, 0, 0, 1, 1, 1, 2, 3.
+  The 3rd smallest of the sorted list is 0.
+
+MY NOTES: So basically flatten the matrix onto an array, sort it,
+pick out element 2.. easy.  BTW, why does the matrix have to be square,
+any matrix could be flattened and sorted.
+
+GUEST LANGUAGE: As a bonus, I've had a go at translating ch-1.pl into C,
+look in the C/ directory for that.
+
+
+Task 2: Max Number
+
+You are given a list of positive integers.
+Write a script to concatenate the integers to form the highest possible value.
+
+Example 1:
+
+  Input: @list = (1, 23)
+  Output: 231
+
+Example 2:
+
+  Input: @list = (10, 3, 2)
+  Output: 3210
+
+Example 3:
+
+  Input: @list = (31, 2, 4, 10)
+  Output: 431210
+
+Example 4:
+
+  Input: @list = (5, 11, 4, 1, 2)
+  Output: 542111
+
+Example 5:
+
+  Input: @list = (1, 10)
+  Output: 110
+
+MY NOTES: First thought: try all combinations.  Second thought: hang on,
+don't we always pick the number with the biggest initial digit, and if
+there's a tie, pick from the numbers with the biggest initial digit the
+one with the biggest prefix?  For example, if we vary example 4 to be:
+Input: @list = (5, 12, 4, 1, 2), the output would be 542121, ie. 5-4-2-12-1.
+Third thought: do I just mean "sort the numbers alphabetically"?
