'''
Write a function that checks the length of the incoming list, if it is greater than 2,
then just keep the first two lengths and return the new content to the caller.

'''
Write a function that checks to get the elements corresponding to all odd bit indices of the incoming list or tuple object,
and return it to the caller as a new list.
'''
