The implementation includes:

Lagrange's Four Square Theorem algorithm(Very useful for competitive programming students will surely get help)(https://en.wikipedia.org/wiki/Lagrange%27s_four-square_theorem)
Comprehensive test cases covering all scenarios (1, 2, 3, and 4 squares)
Proper documentation and code structure
Edge case handling
