改到妈都不认识以后给过了……
但我还是不知道哪里错了
附上修改代码：
```C++
#include <bits/stdc++.h>
using namespace std;
int n;
pair<int,int>q[1000500];
int xx[] = {1,-1,0,0,1,-1,1,-1};
int yy[] = {0,0,1,-1,1,-1,-1,1};
int hei[1005][1005];
int vis[1005][1005];
void bfs(int x,int y,bool &high,bool &low){
vis[x][y]=1;
int cnt = 1;
int j=0,k=0;
q[0] = {x,y};
while(j<=k){
int nx = q[j].first, ny = q[j++].second;
for(int i=0;i<8;i++){
int dx = xx[i]+nx, dy = yy[i]+ny;
if(dx>n or dy>n or dx<1 or dy<1)continue;
if(hei[dx][dy]!=hei[nx][ny]){
if(hei[dx][dy]>hei[nx][ny]){
high = true;
}else{
low = true;
}
}else if(!vis[dx][dy]){
q[++k]={dx,dy};
vis[dx][dy]=1;
}
}
}
}
int main(){
cin>>n;
int f = 0,g = 0;
memset(vis,0,sizeof(vis));
for(int i=1;i<=n;i++){
for(int j=1;j<=n;j++){
cin>>hei[i][j];
}
}
int cnt = 0;
for(int i=1;i<=n;i++){
for(int j=1;j<=n;j++){
if(vis[i][j])continue;
bool high = false,low = false;
bfs(i,j,high,low); //1山峰，2山谷
if(!high)f++;
if(!low)g++;
}
}
cout<<f<<" "<<g<<endl;
}
```
