What I was needing is something like this: Given an N number I needed to print the following pattern: if N = 2 A B AA AB BA BB If N = 3 A B C AA AB AC BA BB BC CA CB CC AAA AAB AAC ABA ABB ABC ACA ACB ACC BAA BAB BAC BBA BBB BBC BCA BCB BCC CAA CAB CAC CBA CBB CBC CCA CCB CCC Recursion seems like a better fit. Doesn't it?
