【判斷奇偶】#4 A. Watermelon

A. Watermelon time limit per test 1 second memory limit per test 64 megabytes input standard input output standard output

One hot summer day Pete and his friend Billy decided to buy a watermelon. They chose the biggest and the ripest one, in their opinion. After that the watermelon was weighed, and the scales showed w kilos. They rushed home, dying of thirst, and decided to divide the berry, however they faced a hard problem.

Pete and Billy are great fans of even numbers, that's why they want to divide the watermelon in such a way that each of the two parts weighs even number of kilos, at the same time it is not obligatory that the parts are equal. The boys are extremely tired and want to start their meal as soon as possible, that's why you should help them and find out, if they can divide the watermelon in the way they want. For sure, each of them should get a part of positive weight.

Input

The first (and the only) input line contains integer number w (1 ≤ w ≤ 100) — the weight of the watermelon bought by the boys.

Output

Print YES, if the boys can divide the watermelon into two parts, each of them weighing even number of kilos; and NO in the opposite case.

Sample test(s) input

8
      

output

YES
      

Note

For example, the boys can divide the watermelon into two parts of 2 and 6 kilos respectively (another variant — two parts of 4 and 4 kilos).

題目的意思是兩個熊孩子分西瓜，但是他們都喜歡偶數，是以他們要偶數重量的西瓜……

是以……除以二咯~ 記得特殊情況2雖然是偶數但是不能别分成2個偶數就行了~ 大 水 題 ^_^

沒有什麼太多想說的，很多題隻需要了解題意就好其實……

#include<stdio.h>  
int main(void)  
{
    int w;
    scanf("%d",&w);
    if(w==2)
    printf("NO");
    else if(w%2)
              printf("NO");
         else printf("YES");
    return 0;
}
