实现代码

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        a:
        while(s.hasNext()){
                    int v1 = s.nextInt();  
                    int v2 = s.nextInt();  
                    if (0 == (v1|v2)){
                        continue;
                    }
                    for(int i = -1000; i <= 1000; i++ ){
                        if(i * (v1-i) == v2){
                            System.out.println("Yes"); 
                            continue a;
                        }
                    }
                    System.out.println("No");
                }  
    }
