input: Write a python function to remove elements of an array that are greater than a given limit.
  assert remove_above_limit([1, 2, 3, 4, 5], 3) == [1, 2, 3]
  assert remove_above_limit([10, 20, 30, 40, 50], 35) == [10, 20, 30]
  assert remove_above_limit([5, 10, 15, 20, 25], 20) == [5, 10, 15, 20]
output: def remove_above_limit(arr, limit):
      return [x for x in arr if x <= limit]
