input: Write a function to measure the performance of any given function.
  assert measure_performance(lambda x, y: x + y, (3, 5))[0] == 8
  assert measure_performance(lambda x, y: x * y, (3, 5))[0] == 15
  assert measure_performance(lambda x, y: x - y, (10, 4))[0] == 6
output: import time

      start_time = time.time()
      result = func(*args)
      end_time = time.time()
      elapsed_time = end_time - start_time
      return result, elapsed_time
