Given set S={1, 2, 3,..., N}. Find two integers, A and B
- import java.util.Scanner;
-
- public class Solution {
- public static void main(String[] args) {
- Scanner in = new Scanner(System.in);
- int T = in.nextInt();
-
- for (int i = 0; i < T; i++) {
- int N = in.nextInt();
- int K = in.nextInt();
-
- int max = 0;
-
- for (int j = 1; j < N; j++) {
- for (int k = j + 1; k <= N; k++) {
- int h = j & k;
- if (h < K && max < h) max = h;
- }
- }
-
- System.out.println(max);
- }
- }
