a数组操作跟b数组一样

#include<bits/stdc++.h>

using ll = long long;

void solve(){
	int n,m;cin>>n>>m;
	priority_queue<ll> qa,qb;
	for(int i=1;i<=n;i++){

		qb.push(x);
	}
	while(!qa.empty()&&!qb.empty()){

			qb.push((b+1)/2);
		}
	}
	if(!qa.empty()||!qb.empty()){
		cout<<"NO"<<endl;
	}
	else cout<<"YES"<<endl;
}

int main() {
	ios::sync_with_stdio(false);
	cin.tie(nullptr), cout.tie(nullptr);
	
	int T = 1;
	cin>>T;
	while (T--) {
		solve();
	}
	
	return 0;
}

可以将b数组拆成跟a数组一样
