+Task 1: String Format
+Submitted by: Mohammad Sajid Anwar
+
+You are given a string and a positive integer.
+
+Write a script to format the string, removing any dashes, in groups of
+size given by the integer. The first group can be smaller than the integer
+but should have at least one character. Groups should be separated by dashes.

+Task 2: Rank Array
+Submitted by: Mohammad Sajid Anwar
+
+You are given an array of integers.
+
+Write a script to return an array of the ranks of each element: the lowest
+value has rank 1, next lowest rank 2, etc. If two elements are the same
+then they share the same rank.
