Where did these numbers come from?

Question

So I have a code here and what I am tring to do is to get max and min value from string("1 2 3 4 5 6 66") and when I tried to make a char array from this string and get from it max and min I am getting 54 as a max and 32 as a min. HOW?

    static void Main(string[] args)
    {
        HighAndLow("1 2 3 4 5 6 66");
    }
    public static string HighAndLow(string numbers)
    {
        char[] liczby = numbers.ToArray();

        int max = liczby.Max();
        int min = liczby.Min();
        
        Console.WriteLine($"{max} {min}");
        return $"{max} {min}";

    }

Answer 1

Look here

https://www.asciitable.com/

You will see that the character 'c' is decimal 54

and that " " (space) has decimal value 32

Answer 2

You're getting the char codes, not the values.

Change

 char[] liczby = numbers.ToArray();

to something like

char[] temp = numbers.Split(' ');
int[] liczby = temp.Select(c => int.parse(c)).ToArray();

    using System;
using System.Collections.Generic;
using System.Linq;

namespace stack
{
  internal class Program
 {
     static void Main(string[] args)
     {
          HighAndLow("1 2 3 4 5 6 66");

      }
        static string HighAndLow(string numbers)
     {
         if (numbers.Length > 0)
         {
                var listnumbers = numbers.Split(' ');
                var max = int.MinValue;
                var min = int.MaxValue;
                foreach (var number in listnumbers)
                {
                 var ent = int.Parse(number);
                    max = ent <= max ? max : ent;
                 min = ent >= min ? min : ent;
             }
                Console.WriteLine("max :"+max+" min: "+min);
                return $"{max} {min}";
            }
          return "empty string";
        }
 }
}

or just replace:

char[] liczby = numbers.ToArray();

with:

var  temp = numbers.Split(' ');
  int[] liczby = temp.Select(c => int.Parse(c)).ToArray();
