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

Sample Output 2

No

Solution in C# (judge verdict: Accepted)

using System;
class main{
	public static void Main(){
		string[] str = Console.ReadLine().Split();
		int a = int.Parse(str[0]), b = int.Parse(str[1]), c = int.Parse(str[2]);
		Console.WriteLine((a < b && b < c ? "Yes" : "No"));
	}
}
