如果有数，那么x ==y 或者 x==y+2，当x为奇数时，结果为x+y-1，否则为x+y；

import java.util.Scanner;public class Main {public static void main(String[] args) {Scanner sc = new Scanner(System.in);int n = sc.nextInt();while(n-->0){int x = sc.nextInt();int y = sc.nextInt();if (x ==y || x==y+2) {if (x%2==1) {System.out.println((x+y-1));}else{System.out.println((x+y));}continue;}System.out.println("No Number");}}
}
