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

Can you tell me on which test case my program fail please ? Thanks.

#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 ...

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

#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 ...

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.
