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;

namespace Range
{
    class Range
    {
        static void Main()
        {
            string input = Console.ReadLine();
            string[] sample = input.Split(' ');
            int[] a = new int[sample.Length];
            for(int i = 0; i < sample.Length; i++)
            {
                a[i] = int.Parse(sample[i]);
            }
            if (a[0] < a[1] && a[1] < a[2])
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }
        }
    }
}
