Strange Problem!
By BanazadehAria, history, 5 years ago, In English

Hi, I have written a simple dp solution for this problem ==> https://codeforces.me/contest/383/problem/D.

But its something strange that it gets accepted without memory optimizes ==> https://codeforces.me/contest/383/submission/68460051

and it doesnt get accepted with memory optimize ( Every state gets update only from before (i-1) So we can only have 2 rows). https://codeforces.me/contest/383/submission/68460038

The only thing that different is in these two solutions is simple memory optimizing.

UPD: solved

Firstly u still have dp array with size 1001 * 20005 (ur optimization in ur code is useless).
Secondly, if u just need to clear ur array before using it (u have the rubbish in ur array when using it)
I submit ur code just adding two lines, check https://codeforces.me/contest/383/submission/68626410
