Easy way to cancel every word in a sentence

Question

Example:

string str = "I am going to reverse myself.";
string strrev = "I ma gniog ot esrever .flesym"; //An easy way to achieve this

I think I need to iterate over each word, and then every letter of each word.

What I did works great. But I need an easy / short way.

C # CODE:

  string str = "I am going to reverse myself.";
  string strrev = "";

  foreach (var word in str.Split(' '))
  {
     string temp = "";
     foreach (var ch in word.ToCharArray())
     {
         temp = ch + temp;
     }
     strrev = strrev + temp + "";
  }
  Console.WriteLine(strrev);  //I ma gniog ot esrever .flesym

Answer 1

Well, here is the LINQ solution:

var reversedWords = string.Join(" ",
      str.Split(' ')
         .Select(x => new String(x.Reverse().ToArray())));

If you are using .NET 3.5, you also need to convert the inverse sequence to an array:

var reversedWords = string.Join(" ",
      str.Split(' ')
         .Select(x => new String(x.Reverse().ToArray()))
         .ToArray());

In other words:

• Divide by spaces
• For each word, create a new word, treating the input as a sequence of characters, cancel this sequence, turn the result into an array, and then call the constructor string(char[])
• ToArray() , .NET 4
• string.Join , .

, . :

// Don't just call it Reverse as otherwise it conflicts with the LINQ version.
public static string ReverseText(this string text)
{
    char[] chars = text.ToCharArray();
    Array.Reverse(chars);
    return new string(chars);
}

, :

new String( word.Reverse().ToArray() )

Reverse() LINQ , String IEnumerable<char>. IEnumerable<char>, . , ToArray(), char[], string.

, :

string s="AB CD";
string reversed = String.Join(" ",
    s.Split(' ')
     .Select(word => new String( word.Reverse().ToArray() ) ));

Answer 3

Linq

String newStr = new String( str.Reverse().ToArray() );

Answer 4

1 -

  public static string reverseString(this string description) {

        char[] array = description.ToCharArray().Reverse().ToArray();

        return new string(array);
    }

2 -

    public static string reverseText(this string description) {

      string [] reversetext=  description.Split(' ').Select(i => i.ToString().reverseString()).Reverse().ToArray();

      return string.Join(" ", reversetext);
    }

Answer 5

I used XOR for sharing here http://en.wikipedia.org/wiki/XOR_swap_algorithm

X := X XOR Y
Y := X XOR Y
X := X XOR Y

WITH#:

public  string ReverseWords(string str)
    {
        StringBuilder strrev = new StringBuilder();
        StringBuilder reversedword = new StringBuilder();

        foreach (var word in str.Split(' '))
        {
            char[] singlesentence = word.ToCharArray();
            int j = singlesentence.Length / 2;
            if (j > 0)
            {
                for (int i = singlesentence.Length - 1, c = 0; i == j; c = c + 1, i = i - 1)
                {


                    singlesentence[c] = (char)(singlesentence[c] ^ singlesentence[i]);
                    singlesentence[i] = (char)(singlesentence[c] ^ singlesentence[i]);
                    singlesentence[c] = (char)(singlesentence[c] ^ singlesentence[i]);

                }
            }

            strrev.Append(singlesentence);
            strrev.Append(" ");
        }
        return strrev.ToString();
    }

Answer 6

//Without Extension Methods Like: Split, ToCharArray, etc..

public string ReverseString(string str="Hai How Are You?"){
    var FullRev="", 
    var wordRev="";
    for(i=0;i<=str.length;i++){
        if(str[i]==" " || i==str.length){
            FullRev=FullRev+" "+wordRev; //FullRev=wordRev+" "+FullRev; 
            wordRev="";
        }else{
            wordRev=str[i]+wordRev;
        }
    }
    return FullRev;
} 
//Result "iaH woH erA ?uoY"
