Function Name:offset

Description:Write a function called offset that indexes into two tuples and returns a tuple. The return tuple will contain,in order, the indices visited. The following are the rules for how you should visit an index:

1. Visittuple_1atindex_1(a parameter).
2. Store the visited index.
3. Visittuple_2at the stored index from step 2.
4. Store the visited index.
5. Repeat steps 1 - 4
6. Stop whenever you reach an index of 0 in either of the two tuples.

Remember to store every index that you visit, includingindex_1(the starting index) and 0 (the ending index), and return those values in a tuple.

To better represent this say we have tuple_1: (3,2,1,0) and tuple_2: (0, 1, 2, 3). The element at index 0 for tuple_1 is 3. This 3 now represents the number which you will use to index into tuple_2. tuple_2 at index 3 is 3. This 3 now represents the number which you will use to index into tuple_1. tuple_1 at index 3 is 0. So now you will stop. The path that you return is: (0, 3, 3, 0)

Parameter(s):

1. tuple_1: A tuple of integers. Each integer is a valid index for theothertuple.

2. tuple_2: A tuple of integers. Each integer is a valid index for theothertuple.

3. index_1: A single integer. The index of where to begin the path in thefirst

   tuple.

Return Value:A new tuple with the path to 0.

Assumption(s):

• The integers in both of the tuples are unique.

• The integers correspond to actual indexes of the other tuple.

• The integer indices will not result in an endless loop.

• Once one of the indices is a 0, you can stop.

  Example(s):

  >>> number_tuple_1 = (6,4,2,7,1,9,3,5,8,0)
  >>> number_tuple_2 = (3,8,1,0,9,6,5,4,7,2)
  >>> index_1 = 4
  >>> print(offset(number_tuple_1, number_tuple_2, index_1)) (4, 1, 8, 8, 7, 5, 6, 3, 0)
