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 main()
{
	int num, i, j, buf, count = 0;
	int a[10][10] = { 0 };

	scanf("%d",&num);
	for (i = 1; i <= num; i++) {
		buf = i;
		while (buf >= 10) buf /= 10;
		a[buf][i % 10]++;//buf是首位数,i%10是末位数
	}
	for (i = 0; i < 10; i++) {
		for (j = 0; j < 10; j++) {
			count += a[i][j] * a[j][i];
		}
	}
	printf("%d\n", count);
	return 0;
}
