Reverse Word Characters in Place

Given a string, Reverse every word in the string in place. For example if you have Ayman Ali, running the algorithm should result in namyA ilA.

Solutions

            //Reverse words in string

            var input = "ayman ali";

            input += " ";

            //Convert into Array

            var arr = input.ToCharArray();

            //Loop Through the array with the length of the array

            var b = 0; //Pointer to an actual element

            var e = 0;

            for (int i = 0; i < arr.Length; i++)

            {

                if (arr[i] == ' ') //Space reached

                {

                    e = i - 1;

                    //Rotate in place

                    for (int p = b; p < e - ((e-b) / 2); p++)

                    {

                        var temp = arr[p];

                        var m = e - (p - b);

                        arr[p] = arr[m];

                        arr[m] = temp;

                    }

                    b = e + 2;

                }

            }

            //If first element note b = Begin of new word

            //IF space or end of string

            //      Record the position as end of word (e)

            //      Rotate the word beginning with b and ending with e

            //      let b = e + 2

            //Else 

            //      Continue

            //End Loop

            //Rotate a word

            //Loop through the word (Length half the word) begin with b and end with e

            //Save Pointer element temporarily

            //Save mirror position (m) into pointer position (p) - Define mirror position 

            //save p into m

            Console.WriteLine(string.Join("",arr.Take(arr.Length-1)));

           //Console.WriteLine(string.Join(",", out));

            Console.ReadLine();
