6的
下次重学cin cout
```cpp
#include <bits/stdc++.h>
using namespace std;
int m;
int sum[2000000];
int main(){
cin >> m;
for(int i = 1;i <= 2000000;i++){
sum[i] = sum[i - 1] + i;
}
for(int i = 1;i <= m / 2 + 1;i++){
for(int j = i;j >= 1;j--){
if(sum[i] - sum[j - 1] > m){
break;
}
if(sum[i] - sum[j - 1] == m && i != j){
cout << j << " " << i << '\n';
}
}
}
return 0;
}
```

```cpp
cout << j,i;
```
输出有问题吧
