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

#define fast_io ios::sync_with_stdio(false),cin.tie(0)
typedef long long ll;

ll power2(int n)
{
	ll ans=1;
	for(int i=0;i<n;i++) ans*=2;
	return ans;
}

int main()
{
	fast_io;

	int t;cin>>t;
	while(t--)
	{
		int h,p;cin>>h>>p;

		ll cnt=0,r=1,nodes=power2(h)-1;
		while(r<p)
		{
			nodes-=r,cnt++;
			r*=2;
		}
		cnt+=(nodes-1)/p+1;
		cout<<cnt<<"\n";
	}
}

Thanks
