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

Sample Output 2

No

Solution in C# (judge verdict: Accepted)

using System;

class Range
{
    public static void Main()
    {
        string[] s = Console.ReadLine().Split();
        int a = int.Parse(s[0]);
        int b = int.Parse(s[1]);
        int c = int.Parse(s[2]);

        if(a < b && b < c)
        {
            Console.WriteLine("Yes");
        }
        else
        {
            Console.WriteLine("No");
        }

    }
}
