@[白井黑子](/space/show?uid=55537) 求大佬帮我看看我这个暴力哪里打错了？
```cpp
#include <bits/stdc++.h>
using namespace std;
int n,m,x[40009];
struct U {
int yi;
int er;
int san;
int si;
};
U fj[40009];
int main() {
scanf("%d %d",&n,&m);
for(int i=1; i<=m; i++) {
scanf("%d",&x[i]);
double(x[i]);
}
for(int a=1; a<=m; a++) {
for(int b=1; b<=m; b++) {
for(int c=1; c<=m; c++) {
for(int d=1; d<=m; d++) {
if(x[a]<x[b]&&x[b]<x[c]&&x[c]<x[d]&&x[b]-x[a]==2*(x[d]-x[c])&&x[b]-x[a]<(x[c]-x[b])/3) {
fj[a].yi++;
fj[b].er++;
fj[c].san++;
fj[d].si++;
}
}
}
}
}
for(int i=1; i<=m; i++) {
printf("%d %d %d %d\n",fj[i].yi,fj[i].er,fj[i].san,fj[i].si);
}
return 0;
}
