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 C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Linq;

class A61 {
		public static void Main(string[] args) {
				int[] input = Console.ReadLine().Split(' ').Select(x => int.Parse(x)).ToArray();
				if(input[0]<=input[2] && input[1] >= input[2]) {
						Console.WriteLine("Yes");
				}else{
						Console.WriteLine("No");
				}
		}
