Consider the following program segment in which the statements are jumbled, choose the correct order of statements to swap two variables using the third variable.

void swap(int a, int b)
{	
  a = b;      → (1)
  b = t;      → (2)
  int t = 0;  → (3)
  t = a;      → (4)
}

1. (1) (2) (3) (4)
2. (3) (4) (1) (2)
3. (1) (3) (4) (2)
4. (2) (1) (4) (3)
