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.

using System;

namespace Project
{
    class Program
    {
        static void Main()
        {
            int n = int.Parse(Console.ReadLine());
            char[] s = Console.ReadLine().ToCharArray();
            int k = int.Parse(Console.ReadLine());
            char r = s[k - 1];
            string res = "";
            foreach(char c in s)
            {
                if(c == r)
                {
                    res += c;
                }else
                {
                    res += "*";
                }
            }
            Console.WriteLine(res);
        }
    }
