Solution: Coin Change
Explore the coin change problem by understanding how to use dynamic programming in Go to minimize the number of coins needed to reach a target amount. Learn to identify base cases, apply memoization using a counter array, and optimize recursive solutions to improve both time and space complexity.
Statement
Given an integer total that represents the target amount of money and a list of integers coins that represents different coin denominations, find the minimum number of coins required to make up the total amount. If it’s impossible to achieve the target amount using the given coins, return -1. If the target amount is 0, return 0.
Note: You can assume that we have an infinite number of each kind of coin.

coins.length -
coins[i] -
