dfs判断条件没写好 会一直搜下去@[CSP_JAKME](/user/973480)

@[somek_](/user/1037054) 那要咋改，只能用递归
by CSP_JAKME @ 2024-04-21 19:09:20
好像还有第一列，斜着的一列为1的，如果不判断的话就死循环了

```
#include<iostream>
using namespace std;
int dfs(int i,int j){
if(i==1&&j==1) return 1;
if(j==1) return 1;
if(i==j) return 1;
return dfs(i-1,j)+dfs(i-1,j-1);
}
int main(){
int i,j;
cin >> i >> j;
cout << dfs(i,j);
return 0;
}
```
