input: Write a python function to take two user inputs as integers and return them as a tuple.
  assert get_user_input() == (1, 2)  # when user inputs 1 and 2 respectively
  assert get_user_input() == (10, 20)  # when user inputs 10 and 20 respectively
  assert get_user_input() == (-5, 15)  # when user inputs -5 and 15 respectively
output: def get_user_input():
      first_input = int(input())
      second_input = int(input())
      return (first_input, second_input)
