input: Write a python function to compute the sum of the squares of all even numbers in a list.
  assert sum_of_squares_of_evens([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) == 220
  assert sum_of_squares_of_evens([10, 20, 45, 67, 84, 93]) == 8500
  assert sum_of_squares_of_evens([5, 7, 9, 8, 6, 4, 3]) == 116
output: def sum_of_squares_of_evens(numbers):
      return sum(x**2 for x in numbers if x % 2 == 0)
