沒什麽了,我沒睡醒。
```c
int Map[21][21] = {};
```
改成
```c
long long Map[21][21] = {};
```
即可

@[sc_lui95](/user/1118234) 我开了longlong也是60，求助
```cpp
#include<bits/stdc++.h>
using namespace std;
long long n,m,q,p,dp[50][50];
int main(){
cin>>n>>m>>q>>p;
for(long long i=0;i<=n;++i){
for(long long j=0;j<=m;++j){
if((i-q)*(i-q)+(j-p)*(j-p)==5||(i==q&&j==p)) dp[i][j]=0;
else if(i==0||j==0){
dp[i][j]=1;
}
else dp[i][j]=dp[i-1][j]+dp[i][j-1];
}
}
cout<<dp[n][m];
return 0;
}
```
