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;

namespace abc061_a
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] ABCs = Console.ReadLine().Split(' ');

            int A = Convert.ToInt32(ABCs[0]);
            int B = Convert.ToInt32(ABCs[1]);
            int C = Convert.ToInt32(ABCs[2]);

            if (A<=C && B>=C)
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }
            Console.ReadLine();
        }
    }
}
