@[ButterflyDew](/space/show?uid=63727) 我不会快速输出dalao来个模板呗

然后你稍微看一下修改的时候能不能去掉几个在树套树上的修改，我看了一下我的代码，一次修改最多改6次

```cpp
namespace io
{
const int SIZE=(1<<21)+1;
char ibuf[SIZE],*iS,*iT,obuf[SIZE],*oS=obuf,*oT=oS+SIZE-1,c,qu[55];
int f,qr;
// getchar
#define gc() (iS==iT?(iT=(iS=ibuf)+fread(ibuf,1,SIZE,stdin),(iS==iT?EOF:*iS++)):*iS++)
// print the remaining part
inline void flush(){fwrite(obuf,1,oS-obuf,stdout);oS=obuf;}
// putchar
inline void putc(char x){*oS++=x;if(oS==oT)flush();}
// input a signed integer
template <class I>
inline void read(I &x)
{
for(f=1,c=gc();c<'0'||c>'9';c=gc()) if(c=='-') f=-1;
for(x=0;c<='9'&&c>='0';c=gc()) x=x*10+(c&15);x*=f;
}
// print a signed integer
template <class I>
inline void print(I &x)
{
if(!x)putc('0');if(x<0) putc('-'),x=-x;
while(x)qu[++qr]=x%10+'0',x/=10;
while(qr)putc(qu[qr--]);
}
//no need to call flush at the end manually
struct Flusher_ {~Flusher_(){flush();}}io_flusher_;
}
using io::read;
using io::putc;
using io::print;
```

修改操作是没有什么问题的我的也是6次，至于刚刚说那个查询时的操作我不太懂你说的意思
