This looks like a classic number theory problem involving quadratic residues! Using Euler's Criterion is definitely the right approach to determine solvability before wasting time searching for a nonexistent . It reminds me of how sometimes you need to check the conditions before launching a planet-destroying attack in Solar Smash; otherwise, your strategy falls flat. Good luck implementing the modular exponentiation for those large inputs!
