Problem:
Range

Write a program which reads three integers a, b and c, and prints "Yes" if a < b < c, otherwise "No".

Input

Three integers a, b and c separated by a single space are given in a line.

Output

Print "Yes" or "No" in a line.

Constraints

0 ≤ a, b, c ≤ 100

Sample Input 1

1 3 8

Sample Output 1

Yes

Sample Input 2

3 8 1

Sample Output 2

No

Solution in C# (judge verdict: Accepted)

using System;

class Range{
    static void Main(){
        
        string str = Console.ReadLine();
        string[] s = str.Split(' ');
        var a = int.Parse(s[0]);
        var b = int.Parse(s[1]);
        var c = int.Parse(s[2]);
        
        if (a < b && b < c){
            Console.WriteLine("Yes");
        }
        else {
            Console.WriteLine("No");
        }
    }
}
