input: Write a python function to find the sum of numbers greater than a given value in a list.
  assert findSum([1, 4, 5, 10, 12], 6) == 22
  assert findSum([2, 8, 3, 15, 7], 5) == 30
  assert findSum([5, 5, 5, 5], 4) == 20
output: def findSum(lst, value):
      return sum(x for x in lst if x > value)
