NP Complexity

blog

Ahhhh, what is P, NP, NP-Complete and NP-hard. Found this quick explanation. Still reading on the subject. I feel like It might take me a lot of time until I can be able to explain that easily to someone who has no idea what it is.

true mastery of a subject is achieved when you can explain it simply

Here’s a stackoverflow pretty simple explanation

A decision problem is in P if there is a known polynomial-time algorithm to get that answer. A decision problem is in NP if there is a known polynomial-time algorithm for a non-deterministic machine to get the answer.
