#include<bits/stdc++.h>
using namespace std;

            if ((A^(tmpa|i))<=B&&B<=(A^(tmpb|j)))
                query(tr[p][i<<1|j],a,b,tmpa|i,tmpb|j,d-1);
}
int main(){
    n=read();q=read();idx=1;
    for (int i=1;i<=n;i++) x[i]=read();
    for (int i=1;i<n;i++) insert(x[i],x[i+1],i),insert(x[i+1],x[i],i);
    for (int i=1;i<=q;i++){
        int a=read(),b=read();ans=-1;
        if (mp.count(a^b)) ans=mp[a^b]; query(1,a,b,0,0);
        printf("%d\n",ans);
    }
    return 0;
}

这程序好像有点Bug,我给组数据试试?
