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 ITP1_2_B {
    public static void Main() {

        string[] Input = Console.ReadLine().Split(' ');

        int a = int.Parse(Input[0]);
        int b = int.Parse(Input[1]);
        int c = int.Parse(Input[2]);

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