求帮求帮啊，兄弟姐妹们

输入一个长整数，判断其低5位是否为回文（个位＝万位，十位＝千位）。如果是输出"this number is a huiwen"，否则输出"this number is not a huiwen"

#include<stdio.h>

int main() {
    int n;
    scanf("%d",&n);
    if (n%10 == n/10000%10 && n/10%10 == n/1000%10) {
        printf("this number is a huiwen");
    } else {
        printf("this number is not a huiwen");
    }
    return 0;
}
