The candy left in the bag

Problem

You're sharing a bag of candy with your friends: everyone gets the same number of whole pieces, and the ones that aren't enough to give each of them one more stay in the bag.

Write a function that takes how many pieces there are and how many friends there are, and returns how many stay in the bag. With 10 pieces and 4 friends, 2 are left. If there's less candy than friends, nobody gets any and all of it stays.

Examples

• 10, 4 → 2

• Shares out evenly

  12, 4 → 0

• Less candy than friends

  3, 5 → 3

Besides these, the challenge has hidden tests that are revealed when you submit your solution.

You start with this

def leftovers(candy, friends):
    pass

function leftovers(candy, friends) {
}
