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 A{
	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");
		}
	
	}
