@[linners](/space/show?uid=47981) 因为记录的是两数间的差值，二分check时要判断maxsa-minsa>mid,而不是>=。
```cpp
bool check(int x,int n)
{
int maxh=sa[1],minh=sa[1];
for(int i=2;i<=n;i++)
{
if(height[i]<x)maxh=minh=sa[i];
else
{
maxh=mymax(maxh,sa[i]);
minh=mymin(minh,sa[i]);
if(maxh-minh>=x)return true;
}
}
return false;
}
```
