Matchsticks to Square

Understand how to apply backtracking techniques to solve the Matchsticks to Square problem, where you must use each given matchstick exactly once to form a perfect square. Learn to develop a logical approach for arrangement, handle constraints, and optimize the solution within given time and space complexity limits.

We'll cover the following...

Statement

Given an integer array, matchsticks, where matchsticks[i] is the length of the ithith matchstick. Use every single matchstick to create a square. No stick should be broken, although they can be connected, and each matchstick can only be used once.

Return TRUE if we can make this square; otherwise, return FALSE.
