`int lo=log2(a-b+1);`
你有没有感觉哪里不对？

```cpp
for(int i=1;i<=21;i++){
for(int j=1;j+(1<<i)-1<=n;j++){
stmin[i][j]=min(stmin[i-1][j],stmin[i-1][j+(1<<(i-1))]);
stmax[i][j]=max(stmax[i-1][j],stmax[i-1][j+(1<<(i-1))]);
```
**cout<<stmax[i][j]<<" "<<stmin[i][j]<<endl;**
```cpp
}
cout<<endl;
}
```
这一行没注释吧

@[IKUN_dashuai](/user/750591) 这里调试代码没删，但与此无关

!!!(a-b+1)改成(b-a+1)就可以AC

@[IKUN_dashuai](/user/750591) 变量命名的时候还是注意点吧
