import java.util.Scanner; public class  a{     public static void main(String[] args) {         Scanner scanner=new Scanner(System.in);                 int n=scanner.nextInt();         long[][] a=new long[n][2];         for(int i=0;i<n;i++){             a[i][0]=scanner.nextLong();             a[i][1]=scanner.nextLong();                     }         for(int i=0;i<n;i++){             System.out.println(printY(a[i][0],a[i][1]));         }     }     public static long printY(long a,long a2){         long i=0;         int count=0;         while(count<a2){             if((a+i)==(a|i)){                 count++;             }             i++;         }                 return i;             }      } 是这样吗?但是我的是超时的，然后通过率是0，哎花了好长时间....大佬能帮我解答一下吗？
