暴力枚举1234567和123456的系数

#include <bits/stdc++.h>
#define INF 1e9
using namespace std;
typedef long long ll;

int main(){

int n;

cin >> n;
for(ll i = 0; i * 1234567 <= n; i++)
for(ll j = 0; j * 123456 + i * 1234567 <= n; j++){

int d = n - i * 1234567 - j * 123456;
if(d % 1234 == 0){
cout << "YES" << endl;
return 0;
}
}
cout << "NO" << endl;
return 0;
}

Kolya is developing an economy simulator game. His most favourite part of the development process is in-game testing. Once he was entertained by the testing so much, that he found out his game-coin score become equal to 0.

Kolya remembers that at the beginning of the game his game-coin score was equal to n and that he have bought only some houses (for1 234 567 game-coins
each), cars (for 123 456 game-coins each) and computers (for 1 234 game-coins
each).

Kolya is now interested, whether he could have spent all of his initial n game-coins buying only houses, cars and computers or there
is a bug in the game. Formally, is there a triple of non-negative integers a, b and c such
thata × 1 234 567 + b × 123 456 + c × 1 234 = n?

Please help Kolya answer this question.

Input

The first line of the input contains a single integer n (1 ≤ n ≤ 109) —
Kolya's initial game-coin score.

Output

Print "YES" (without quotes) if it's possible that Kolya spent all of his initial n coins
buying only houses, cars and computers. Otherwise print "NO" (without quotes).

Examples

input
1359257


output
YES


input
17851817


output
NO


Note

In the first sample, one of the possible solutions is to buy one house, one car and one computer, spending1 234 567 + 123 456 + 1234 = 1 359 257 game-coins
in total.
