Problem: Matchsticks to Square

med
30 min
Explore how to apply backtracking algorithms to solve the Matchsticks to Square problem, where you use each matchstick once to form a square without breaking any. Understand the problem constraints, logic, and practice implementing an efficient solution to enhance your coding interview preparation.

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.

Constraints:

  • 11 \leq matchsticks.length 15\leq 15

  • 11 \leq matchsticks[i] 103\leq 10^3
