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

            int N = Convert.ToInt32(line);
            int count = 0;
            int[][] c = new int[10][];
            for (int i = 0; i < 10; i++)

                c[i] = new int[10];
            }

            for (int i = 1; i < N +1; i++)
            {
                c[Convert.ToInt32(i.ToString().Substring(0, 1))][Convert.ToInt32(i.ToString().Substring(i.ToString().Length - 1, 1))] += 1;
            }

            for (int j = 1; j <= 9; j++)

                for (int k = 0; k <= 9; k++)
                {
                    count += c[j][k] * c[k][j];
                }
