Does it have any patterns? Or it is random! :) – Hosein Rahnama Nov 01 '15 at 18:05
Pattern in Input? – vidhan Nov 01 '15 at 18:06
Inputs are random. – vidhan Nov 01 '15 at 18:09
Nope, I mean is there really a relation or pattern between input and output? – Hosein Rahnama Nov 01 '15 at 18:45
Where did you get this? – Nov 01 '15 at 18:54
I found the pattern.Suppose first input is n and second m then the answer is sum of square of digits of n m number of times. – vidhan Nov 01 '15 at 18:55
Good for you. You knew it before asking this question, I'm sure – Nov 01 '15 at 19:11
