#include <stdio.h>

int main()
{
    char a[3],b[3];
    gets(a);
    gets(b);
    int x;
    if (a[3]=='0'||a[3]=='2'||a[3]=='4'||a[3]=='6'||a[3]=='8')
        x=1;
    if (b[3]=='1'||b[3]=='3'||b[3]=='5'||b[3]=='7'||b[3]=='9')
        x=1;
   if(x==1) printf("yes");
     else printf("no");
}

The two codes are just two numbers, think about it this way. If I write more, the solution will be obvious and you will get nothing.
