Problem:
Score : 100 points

Problem Statement

There are three houses on a number line: House 1, 2 and 3, with coordinates A, B and C, respectively.
Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Constraints

0\leq A,B,C\leq 100

A, B and C are distinct integers.

Input

Input is given from Standard Input in the following format:

A B C

Output

Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Sample Input 1

3 8 5

Sample Output 1

Yes

We pass the coordinate 5 on the straight way from the house at coordinate 3 to the house at coordinate 8.

Sample Input 2

7 3 1

Sample Output 2

No

Sample Input 3

10 2 4

Sample Output 3

Yes

Sample Input 4

31 41 59

No

Solution in C# (.NET Core 3.1.201) (judge verdict: Accepted)

using System;

namespace A
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] In = Console.ReadLine().Split(' ');
            int a = int.Parse(In[0]);
            int b = int.Parse(In[1]);
            int c = int.Parse(In[2]);
            if((a<=c && c<=b )|| (b <= c && c <= a))
            {
                Console.WriteLine("Yes");
            }
            else
            {
                Console.WriteLine("No");
            }
        }
    }
