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
