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: Runtime Error)

using System;

namespace Range
{

	class Range
	{
		static void Main()
		{
            string tmp;
            int a;
            int b;
            int c;
            tmp = Console.ReadLine();

            a = int.Parse(tmp.Substring(0, 1));
            b = int.Parse(tmp.Substring(2, 1));
            c = int.Parse(tmp.Substring(4, 1));
            
            if(a < b)
			{
				if(b < c)
				{
					Console.WriteLine("Yes");
				}
				else
				{
					Console.WriteLine("No");
				}
			}
			else
			{
				Console.WriteLine("No");
			}

		}
	}
