Split a random value into four that sum up to it

Question

I have one value like 24, and I have four textboxes. How can I dynamically generate four values that add up to 24?

All the values must be integers and can\'t be nega

Answer 1

func getRandomValues(amountOfValues:Int, totalAmount:Int) -> [Int]?{
    if amountOfValues < 1{
        return nil
    }

    if totalAmount < 1{
        return nil
    }

    if totalAmount < amountOfValues{
        return nil
    }

    var values:[Int] = []
    var valueLeft = totalAmount

    for i in 0..

This is not a final answer, but it should be a (good) starting point.

How it works: It takes 2 parameters. The amount of random values (4 in your case) and the total amount (24 in your case).

It takes a random value between the total Amount and 0, stores this in an array and it subtracts this from a variable which stores the amount that is left and stores the new value.

Than it takes a new random value between the amount that is left and 0, stores this in an array and it again subtracts this from the amount that is left and stores the new value.

When it is the last number needed, it sees what amount is left and adds that to the array

EDIT:

Adding a +1 to the random value removes the problem of having 0 in your array.

EDIT 2:

Shuffling the array does remove the increased chance of having a high value as the first value.
