Master the Minimum Number of Coins (Coin Change Problem) using Dynamic Programming.
In this video, we cover:
🔹 Recursion approach (brute force)
🔹 Memoization (top-down DP)
🔹 Tabulation (bottom-up DP)
🔹 Common mistakes (INT_MAX, overflow, edge cases)
🔹 Optimized solution
By the end, you’ll clearly understand how to solve this classic DP problem and apply the same pattern to similar questions.
💻 Problem:
Given coins and a target amount, find the minimum number of coins needed to make that amount. If not possible, return -1.
