Complexity classes are categories used in computational complexity theory to classify problems based on their inherent difficulty and the resources required to solve them, such as time and space. Here’s a list of some fundamental complexity classes: 1. **P**: - Problems that can be solved in polynomial time by a deterministic Turing machine. 2. **NP**: - Nondeterministic Polynomial time.
