Problem Statement

E869120 has A 1-yen coins and infinitely many 500-yen coins.

Determine if he can pay exactly N yen using only these coins.

Constraints

N is an integer between 1 and 10000 (inclusive).

A is an integer between 0 and 1000 (inclusive).

Input

Input is given from Standard Input in the following format:

N
A

Output

If E869120 can pay exactly N yen using only his 1-yen and 500-yen coins, print Yes; otherwise, print No.

Sample Input 1

2018
218

Sample Output 1

Yes

We can pay 2018 yen with four 500-yen coins and 18 1-yen coins, so the answer is Yes.

Sample Input 2

2763
0

Sample Output 2

No

When we have no 1-yen coins, we can only pay a multiple of 500 yen using only 500-yen coins. Since 2763 is not a multiple of 500, we cannot pay this amount.

Sample Input 3

37
514

Sample Output 3

Yes

import java.util.Scanner;

    int N;
    int A;
    System.out.println("何円を調べるか");
    N=sc.nextInt();
    System.out.println("一円玉の枚数(A<1000)");
    A=sc.nextInt();
    while(N>500){
      N=N-500;
      //System.out.println("N="+N);
    }
    if(A>=N){
      System.out.println("Yes");
    }else{
      System.out.println("No");
