DSA Pattern: Dynamic Programming (DSA Patterns)

DP problem-solving techniques and patterns

Pattern Overview

When to Use

Overlapping subproblems
Optimal substructure
Counting paths

Top-down or bottom-up
Polynomial time for NP-hard
Systematic approach

Example Problems

Classic 1D DP

Coin Change

Unbounded knapsack variant

Edit Distance

2D string DP
