Problem Statement

AtCoDeer has three cards, one red, one green and one blue.

An integer between 1 and 9 (inclusive) is written on each card: r on the red card, g on the green card and b on the blue card.

We will arrange the cards in the order red, green and blue from left to right, and read them as a three-digit integer.

Is this integer a multiple of 4?

Constraints

1 ≤ r, g, b ≤ 9

Input

Input is given from Standard Input in the following format:

r g b

Output

If the three-digit integer is a multiple of 4, print YES (case-sensitive); otherwise, print NO.

Sample Input 1

4 3 2

Sample Output 1

YES

432 is a multiple of 4, and thus YES should be printed.

Sample Input 2

2 3 4

Sample Output 2

NO

234 is not a multiple of 4, and thus NO should be printed.

#include <stdio.h>
int main(void){
    int a=0,b=0,n,i;
    char c,st[101]="";
    scanf("%d",&n);
    getchar();
    for(i=0;i<n;i++){
        scanf("%c",&c);
        st[i]=c;
        if(c=='('){
            a++;
        }
        else{
            if(a>0){
                a--;
            }
            else{
                b++;
            }
        }
    }
    for(i=0;i<b;i++){
        printf("(");
    }
    printf("%s",st);
    for(i=0;i<a;i++){
        printf(")");
    }
}
