Dynamic Programming (DP) solves problems that have overlapping subproblems and optimal substructure — the answer is built from answers to smaller versions of the same problem, and those smaller answers repeat. Instead of recomputing them (exponential time), we store and reuse them.
Two styles: top-down (recursion + memoisation — cache each result the first time you compute it) and bottom-up (tabulation — fill an array from the smallest subproblem upward). The classic first example is Fibonacci: naive recursion is O(2ⁿ), but with memoisation it drops to O(n).
