answer

#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;
}
