input: Write a function to filter a list of integers and return only those values that are greater than 50 using a lambda expression. The function should take a list of integers as input and return the filtered list.
  assert filter_greater_than_50([45, 12, 52, 89, 33, 99])==[52, 89, 99]
  assert filter_greater_than_50([10, 20, 30, 40, 50])==[]
  assert filter_greater_than_50([60, 70, 80, 90, 100])==[60, 70, 80, 90, 100]
  assert filter_greater_than_50([50, 51, 52, 53])==[51, 52, 53]
  assert filter_greater_than_50([])==[]
output: def filter_greater_than_50(lst):
      return list(filter(lambda x: x > 50, lst))
