Assume the parameters in the following code are being passed by reference. What numbers reside in the variables a and b after the swap takes place? Next, assume the parameters are being passed by value-result. What numbers reside in the variables a and b after the swap takes place this time? void swap(int x, int y, int z) {     int tmp = x;     x = y;     y = z;     z = tmp; } int main() {     int a = 3;     int b = 4;     swap(a, b, b); }
