Problem Statement

You are given three integers A, B and C.
Determine whether C is not less than A and not greater than B.

Constraints

-100≤A,B,C≤100

A, B and C are all integers.

Input

Input is given from Standard Input in the following format:

A B C

Output

If the condition is satisfied, print Yes; otherwise, print No.

Sample Input 1

1 3 2

Sample Output 1

Yes

C=2 is not less than A=1 and not greater than B=3, and thus the output should be Yes.

Sample Input 2

6 5 4

Sample Output 2

No

C=4 is less than A=6, and thus the output should be No.

Sample Input 3

2 2 2

Sample Output 3

Yes

Solution in Python (3.4.3) (judge verdict: Accepted)

def between_two_integers(A: int, B: int, C: int)->bool:
    return A <= C and C <= B


if __name__ == "__main__":
    A, B, C = map(int, input().split())
    yes = between_two_integers(A, B, C)
    print('Yes' if yes else 'No')
