Coin change problem using greedy algorithm

WebMar 20, 2024 · Examples of Greedy Algorithms Coin changing problem: Given a collection of currency denominations, this problem aims to determine the smallest number of coins required to create a certain amount of change. For this task, a greedy algorithm repeatedly selects the most significant coin denomination that fits inside the remaining … WebDec 16, 2024 · This problem is a variation of the problem discussed Coin Change Problem. Here instead of finding the total number of possible solutions, we need to find the solution with the minimum number of coins. The minimum number of coins for a value V can be computed using the below recursive formula. If V == 0, then 0 coins required.
