input: Write a function to create a lambda expression in Python to filter a list of integers greater than 50. The function should take a list as input and return the filtered list.
  
  assert filtered_list([45, 12, 52, 89, 33, 99])==[52, 89, 99]
  assert filtered_list([10, 20, 30, 40, 50])==[]
  assert filtered_list([60, 70, 80, 90, 100])==[60, 70, 80, 90, 100]
  assert filtered_list([])==[]
  assert filtered_list([51, 49, 52, 48, 53])==[51, 52, 53]
output: return list(filter(lambda x: x > 50, lst))
