Challenge 7: The Coin Change Problem
Let's solve a coding challenge on the different ways to represent a given number of cents.
We'll cover the following
Problem Statement
Given an infinite number of quarters (25 cents), dimes (10 cents), nickels (5 cents), and pennies (1 cent), write code to calculate the number of ways to represent n
cents.
Input
The values of the coins available to represent the cents with (the denominations), the number of denominations, and the number of cents.
Output
The number of ways that the given number of cents can be represented.
Sample Input
int amount = 10;
int denoms = {25, 10, 5, 1}
int denomsLength = 4;
Sample Output
4
Coding Exercise
Take a close look and design a step-by-step algorithm before jumping on to the implementation. This problem is designed for your practice, so try to solve it on your own first. If you get stuck, you can always refer to the hint and solution provided in the code tab. Good Luck!
