Write a Swift program that accept two integer values and return true if one of them is 20 or if their sum is 20.

func make_20(x: Int, y: Int) -> Bool {
    if x + y == 20 || x == 20 || y == 20
    {
        return true
    }
    else
    {
        return false
    }
}

print(make_20(x: 29, y: 10))
print(make_20(x: 20, y: 17))
print(make_20(x: 11, y: 9))

Output:

false
true
true
