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;

namespace Range {
    class Program {
        static void Main(string[] args) {
            string[] N = Console.ReadLine().Split(' ');
            int a = int.Parse(N[0]);
            int b = int.Parse(N[1]);
            int c = int.Parse(N[2]);

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