PS. there is a rule-change on Topcoder SRM rules regarding pre-written code, effective now. See the thread at this link and the full rules here.

I have a question about the 30% pre-written code. Does this deduct my point? Or just a warning? Honestly, this rule doesn't make sense much cause many people put their personal library in the code regardless of the use.

My Div-2 600 failed because I used recursion+memoization, the same exact code works fine on my machine and also I tried it on Codeforces custom tests and it works fine,the limits are pretty small and the code run pretty fast so I didn't expect that to exceed the stack size, is that intended?

Code

I know it's better to test on the topcoder itself but sometimes I just test on my machine, and honestly I didn't expect that :/

Can any one tell why this fails? Or provide the test case?

    It's trivial to construct a case where v%c is increasing but $$$s=f$$$ and an answer exists.
