太草了，自己找到了
```cpp
inline int sgtquery(
int tv,
int p = 1, int l = 1, int r = sarn
) {
if(l == r) {
//if(tv < sgt[p]) return 0;
return sgn[p];
}
int mid = (l + r) >> 1;
if(tv <= sgt[ls(p)]) return sgtquery(tv, ls(p), l, mid);
else return sgn[ls(p)] + sgtquery(tv, rs(p), mid + 1, r);
}
```
那个地方沙雕般的注释掉了……
不知道官方会wa多少分QAQ
