input: Write a python function to get the value at a specific index from a list of lists.
  assert getValueAtIndex([[1, 2, 3], [4, 5, 6], [7, 8, 9]], 1) == [4, 5, 6]
  assert getValueAtIndex([[10, 20], [30, 40], [50, 60]], 2) == [50, 60]
  assert getValueAtIndex([['a', 'b'], ['c', 'd'], ['e', 'f']], 0) == ['a', 'b']
output: def getValueAtIndex(list_of_lists, index):
      return list_of_lists[index]
