Problem Description
Two planets named Haha and Xixi in the universe and they were created with the universe beginning.
There is 73 days in Xixi a year and 137 days in Haha a year.
Now you know the days N after Big Bang, you need to answer whether it is the first day in a year about the two planets.
Input
There are several test cases(about 5 huge test cases).
For each test, we have a line with an only integer N(0≤N), the length of N is up to 10000000.
Output
For the i-th test case, output Case #i: , then output "YES" or "NO" for the answer.
Sample Input
10001
0
333
Sample Output
Case #1: YES
Case #2: YES
Case #3: NO

问题简述:(略)
问题分析:
这是一个大数模除问题,需要根据余数定理进行计算。输入的数位数很多,需要用字符串数组来存储。
程序说明:(略)

题记:(略)
AC的C语言程序如下:
/* HDU5832 A water problem */
#include <stdio.h>
#define MOD 10001
#define N 10000000
char s[N + 1];
int main(void)
{
int ans, caseno = 0, i;
while(scanf("%s", s) != EOF) {
ans = 0;
for(i = 0; s[i]; i++)
ans = (ans * 10 + s[i] - '0') % MOD;
printf("Case #%d: %s\n", ++caseno, ans ? "NO" : "YES");
}
return 0;
}
