input: Write a function to remove all occurrences of the given element in the given array and return the modified array. If the given array is empty return an empty list.
  def remove_element(arr, element):
      arr = [x for x in arr if x != element]
      return arr
  
  assert remove_element([2, 4, 5, 7, 4, 2], 4)==[2, 5, 7, 2]
  assert remove_element([3, 2, 4, 6, 2, 8, 2], 2)==[3, 4, 6, 8]
  assert remove_element([1, 1, 1, 1], 1)==[]
  assert remove_element([], 5)==[]
output: def remove_element(arr, element):
      arr = [x for x in arr if x != element]
