Question

Solution

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
		// create a buffered reader
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        int t = Integer.parseInt(br.readLine());
        while (t-- > 0)
        {
            String[] strs = br.readLine().split(" ");
            long a = Long.parseLong(strs[0]);
            long b = Long.parseLong(strs[1]);
            boolean result = (b & (b - 1)) == 0;
            System.out.println((result) ? "Yes" : "No");
        }
        br.close();
	}
}

@anon47473735 use a fast output method… like printwriter. I also committed the same mistake during the contest, but later come to know about it through a post!

            bw.write((result) ? "YES" : "NO" + "\n");
        }
        bw.flush();
	}
}

@anon47473735 try bw.println() instead of bw.write(), maybe that could solve your problem, Also you have to append “\n” with both of them in order to get proper result.
