#include<bits/stdc++.h>
using namespace std;
int main()
{
ios_base::sync_with_stdio(false);
int T;
cin>>T;
while(T--)
{
int n,m;
cin>>n>>m;
auto check=[&](int x)
{
int cnt=0;
for(int i=1;i<=n;i++)
{
if(i%(x+1)!=0)cnt++;
}
return cnt>=m;
};
int l=0,r=m;
while(l<r)
{
int mid=(l+r)/2;
if(check(mid))
r=mid;
else
l=mid+1;
}
cout<<m<<' '<<l<<"\n";
}
return 0;
}
这程序好像有点Bug，我给组数据试试？
