DWITE Online Computer Programming Contest, December 2010, Problem 2
Rectangles can be constructed out of smaller squares. Given a supply of unit squares ( in size), how many unique rectangles can be constructed?
The input will contain 5 lines, each an integer , a number of unit squares available.
The output will contain 5 lines, each a number of unique rectangles that can be constructed from up to unit squares (not all squares have to be used for some of the rectangles).
Note: a rectangle is unique if another rectangle that had previously been constructed can't be rotated to look the same way. That is, and are considered to be the same.
