Didn't know that was necessary o_O . Thanks a lot

Can you tell me on which test case my program fail please ? Thanks. /* ID: lehuydu1 PROG: LANG: C++ */ #include <bits/stdc++.h> using namespace std; #define x first #define y second typedef long long ll; typedef double rl; typedef pair<int,int> pt; int dx[5]={0,0,0,1,-1}, dy[5]={0,1,-1,0,0}; const l...

I've found the mistake, it's not about the precision error. I forgot to add some edges . Thanks for helping anyway.

/* ID: lehuydu1 PROG: LANG: C++ */ #include <bits/stdc++.h> using namespace std; #define x first #define y second #define xx first.first #define xy first.second #define yx second.first #define yy second.second #define cint const int typedef long long ll; typedef double rl; typedef pair<int,int> pt;...

Can someone check my code for me ? I can't find the mistake :( I binary search the answer then perform maximal matching. Thanks in advance. /* ID: lehuydu1 PROG: LANG: C++ */ #include <bits/stdc++.h> using namespace std; #define x first #define y second #define xx first.first #define xy first.second...
