#include <string.h>

void A(char *s)
{
    int len = strlen(s);
    char *p = s + len - 1;
    if (strchr(s, '.'))
    while (*p == '0') *p-- = 0;
    if (*p == '.') *p = 0;
}

int main(void)
{
    char *pa, *pb;
    char a[100024], b[100024];

    while (scanf("%s%s", &a, &b) != EOF)
    {
        pa = a; pb = b;
        while (*pa == '0') pa++;
        while (*pb == '0') pb++;
        A(pa); A(pb);
        puts(strcmp(pa, pb) ? "NO" : "YES");
    }

    return 0;
