Leetcode 3592 - Inverse Coin Change | DP Explained in Java

In this video, we solve Leetcode Problem 3592 - Inverse Coin Change. You're given an array numWays[] where numWays[i] represents the number of ways to make amount i using an unknown set of coin denominations. The challenge is to reverse-engineer this array to find the original coin denominations.

We’ll walk through:

Understanding the inverse coin change concept

Using dynamic programming (DP) to simulate the forward process

Matching with the given numWays[] array

Validating the denominations that could produce the exact number of combinations

📌 Topics Covered:

Dynamic Programming (DP)

Knapsack-style DP construction

Pattern recognition from result arrays

Java implementation walkthrough
