Dynamic Programming
Dynamic Programming (DP) is an optimization technique used to solve complex problems by breaking them into smaller overlapping subproblems and storing their results to avoid recomputation. It improves efficiency using memoization or tabulation. DP is ideal for problems involving recursion, optimal decisions, and constraints, such as knapsack, longest subsequences and shortest paths in graphs.
