I solved D-Lakes in Berland(Round #375 Div2) in the contest and I got Accepted,
Link : http://codeforces.com/contest/723/problem/D
My submission : http://codeforces.com/contest/723/submission/21161297
However after the contest I found a counter test that my code gets wrong , here it is :
the output should be 2304 (changes) instead the output is 0 ,
the problem is that I was looping from 1 to 500 instead of 2500 .
is the test right ? is there a bug in the system test ?
