Bitbucket is for the code that takes us to Mars, decodes the human genome, or drives your next car. What will your code do? Get started with Bitbucket today, it's free.

It's Thursday, so time for another code puzzler. The idea is simple: solve the coding problem as efficiently as you can, in any language or framework that you find suitable.

Note: Even though there really is nothing stopping you from finding a solution to this on the internet, try to keep honest, and come up with your own answer.  It's all about the participation!

Change Calculator 

Say you are given an infinite number of coins in the following denominations: 

  • 25 cents
  • 10 cents
  • 5 cents
  • 1 cent
Write a method that would take an integer parameter named change. Work out all the permutations that can return that amount given the coins that you have available. For example, calculateChange(5) would return 

1 x 5c 
5 x 1c
