The peekBack fails in 1 case
If I insert 1,2,3 and then do a remove. The peekBack checks the inStack which is empty right now and tries to get the peek of an empty stack whereas all the elements have been transferred to outStack.
Please handle this case and also test few other borderline cases

Created two "peek" functions rather than one since it makes it easier to understand on how this queue actually functions.
