# change_greedy

change_greedy, a Python code which uses the greedy method to seek a solution to the change making problem, which tries to match a given amount by selecting coins of various denominations.

If there is a coin of value 1, then there is always at least one solution to the change making problem.

If the coin denominations are ``canonical'', then the greedy method is always guaranteed to come up with a solution, and this solution will involve the fewest possible number of coins.

If the coin denominations are not canonical, then the greedy method may return a solution which does not use the minimum number of coins, or it may fail to find a correct solution at all.

### Languages:

change_greedy is available in a MATLAB version and a Python version.
