Write a function called findNumber that takes a list and a number as parameters. The function returns a new list containing the positions in the argument list where the number was found. The function returns an empty list if the number was not found. For example: If the list that is passed to the function contains [2, 4, 1, 2, 3, 2, 71 and the number we are looking for is 2. The call to findNumber should return the list [0, 3, 5]. That is, the number 2 was found in positions 0, 3 and 5 in the list.
