DP Class Notations

DP class notations describe the complexity of counting problems related to dynamic programming. "DP" stands for "Dynamic Programming," a method for solving complex problems by breaking them into simpler subproblems. The notation "DP" indicates that a problem's solution involves subproblems with overlapping results, and it can be solved efficiently through memoization or tabulation. Often, these classes specify whether counting solutions is feasible within certain resource constraints, such as polynomial time (P) or non-deterministic polynomial time (NP). In essence, DP class notation helps categorize problems based on how difficult they are to solve or count solutions for, guiding expectations about computational feasibility.
