Statement
Given an integer, n, return the least number of perfect square numbers that sum to n.
A perfect square is an integer that is the square of an integer. In other words, it is an integer that is the result of multiplying a whole integer by itself. For example,
, , , and are perfect squares, but , , and are not.
