One Byte Explainer : NP-Complete Problems

This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer.

Explainer

Are you talking about a CS problem and its solution, such that you can prove your solution without getting frustrated? Can you convert other similar CS problems to your problem, but don't know how to accurately solve your problem yet? You have an NP-complete problem in your hand.

Additional Context

CS - Computer Science.
NP-Complete - Non-deterministic Polynomial Complete problem.

Proving your solution for a problem without getting frustrated means that the correctness of the solution for the problem can be checked with polynomial time complexity, like O(n²) or even O(n¹⁰).
