Input : abcOutput : a, b, c, ab, bc, ac, abc, Input : aaaOutput : a, a, a, aa, aa, aa, aaa, Time Complexity: O(m + n), where m and n are numbers of nodes in the first and second lists respectively.

I would rather recommend to create characters array from the initial String and use the array. Is there any known 80-bit collision attack? Let's start with start=0 and end=1. Looks about as efficient and clean as a recursive program of that nature should be. Next figure out your non-self-referencing base cases: 1. substrings ("") = empty set.
