题目描述
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 (for 1 234 567 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 that a × 1 234 567 + b × 123 456 + c × 1 234 = n?
Please help Kolya answer this question.
科里亚正在开发一款经济模拟游戏。他最喜爱的开发环节是游戏内测试。有一次,他沉迷于测试,以至于发现自己的游戏金币数量变为 0。
科里亚记得,游戏开始时他的游戏金币数量为 n,并且他只购买了若干栋房屋(每栋售价 1234567 枚游戏金币)、若干辆汽车(每辆售价 123456 枚游戏金币)以及若干台电脑(每台售价 1234 枚游戏金币)。
科里亚现在想知道:他是否有可能恰好花光初始的 n 枚游戏金币,仅通过购买房屋、汽车和电脑来实现?还是说游戏中存在一个漏洞?形式化地说,是否存在一组非负整数 a、b 和 c,使得
a×1234567+b×123456+c×1234=n?
请帮助科里亚回答这个问题。
输入格式
The first line of the input contains a single integer n (1 ≤ n ≤ 109) — Kolya's initial game-coin score.
输入的第一行包含一个整数 n(1 ≤ n ≤ 109)—— Kolya 初始的游戏币得分。
输出格式
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).
如果科里亚有可能仅用初始的 n 枚硬币购买房屋、汽车和计算机,并恰好花光所有硬币,则输出 "YES"(不带引号);否则输出 "NO"(不带引号)。

说明/提示
In the first sample, one of the possible solutions is to buy one house, one car and one computer, spending 1 234 567 + 123 456 + 1234 = 1 359 257 game-coins in total.
在第一个样例中,一种可能的方案是购买一栋房子、一辆汽车和一台电脑,总共花费 1234567+123456+1234=1359257 枚游戏币。
