Score : 100 points

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# (.NET Core 3.1.201) (judge verdict: Accepted)

using System;

class Program
{
  static void Main(string[] args)
  {
    var input = new Input();
    if (input.C >= input.A && input.C <= input.B)
    {
      Console.WriteLine("Yes");
    }
    else
    {
      Console.WriteLine("No");
    }
  }
}

class Input
{
  public int A { get; set; }
  public int B { get; set; }
  public int C { get; set; }

  public Input()
  {
    var line = Console.ReadLine().Split(" ");
    this.A = int.Parse(line[0]);
    this.B = int.Parse(line[1]);
    this.C = int.Parse(line[2]);
  }
}
