Question

We want make a package of goal kilos of chocolate. We have small bars (1 kilo

each) and big bars (5 kilos each). Return the number of small bars to use, assuming

we always use big bars before small bars. Return -1 if it can't be done.

makeChocolate(4, 1, 9) → 4

makeChocolate(4, 1, 10) → -1

makeChocolate(4, 1, 7) → 2

Skeleton of the method you should use to return the number:

public int makeChocolate(int small, int big, int goal) {

}

Answer 1

public static void main(String[] args) {
    System.out.println(makeChocolate(4,1, 9));
    System.out.println(makeChocolate(4,1,10));
    System.out.println(makeChocolate(4,1,7));

}

public static int makeChocolate(int small, int big, int goal) {
    int tmp = goal - big - small;
    if (tmp > small) {
        return -1;
    } else {
        return tmp;
    }
}
