Problem Statement

Takahashi is participating in a programming contest, AXC001. He has just submitted his code to Problem A.

The problem has N test cases, all of which must be passed to get an AC verdict.

Takahashi's submission has passed M cases out of the N test cases.

Determine whether Takahashi's submission gets an AC.

Constraints

1 \leq N \leq 100

0 \leq M \leq N

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N M

Output

If Takahashi's submission gets an AC, print Yes; otherwise, print No.

Sample Input 1

3 3

Sample Output 1

Yes

All three test cases have been passed, so his submission gets an AC.

Sample Input 2

3 2

Sample Output 2

No

Only two out of the three test cases have been passed, so his submission does not get an AC.

Sample Input 3

1 1

Sample Output 3

Yes

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include<stdio.h>
int n,a[10][10],buf,ans=0;

int main(void)
{
    scanf("%d", &n);
    for (int i = 1; i <= n;i++){
        int buf = i;
        while(buf>=10)
            buf /= 10;
        a[buf][i % 10]++;
    }
    for (int i = 1; i < 10;i++)
        for (int j = 1; j < 10;j++)
            ans += a[i][j] * a[j][i];
    printf("%d", ans);
    return 0;
}
