input: Write a function to compute the sum of two variables and store the result in a third variable. The function should then print the result. The function should take two parameters, x and y, which are the two variables to be summed.
  assert compute_sum(5, 8)==13
  assert compute_sum(0, 0)==0
  assert compute_sum(-1, 1)==0
  assert compute_sum(-5, -5)==-10
  assert compute_sum(10, 20)==30
output: def compute_sum(x, y):
      result = x + y
      print(result)
