Strange Problem!
Difference between en1 and en2, changed 11 character(s)
Hi,↵
I have written a simple dp solution for this problem ==> https://mirror.codeforces.com/contest/383/problem/D.↵
↵
But its something strange that it gets accepted without memory optimizes ==> ↵
https://mirror.codeforces.com/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).↵

↵
The only thing that different is in these two solutions is simple memory optimizing.↵
↵
↵
UPD: solved
