Solution: Perfect Squares
Explore how to solve the perfect squares coding problem by applying number theory concepts like the Four-Square and Three-Square theorems. Learn an efficient algorithm that determines the minimum count of perfect squares summing to an integer through mathematical checks rather than brute force, with constant space and reduced time complexity.

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,
, ...
