Review a solution to the reverse words in a sentence challenge

  • 2 minutes

The following solution provided is one of many possible solutions. The approach taken to solve this challenge was to break down the solution into four steps:

  1. Split the pangram string on the space character to create the string array message.
  2. Create a new newMessagearray that will store a reversed copy of the "word" string from the message array.
  3. Loop through each element in the message array, reverse it and store this element in newMessage array.
  4. Join "word" strings from the array newMessage, using a space again, to create the desired single string to write to the console.

The final result of this example solution.

string pangram = "The quick brown fox jumps over the lazy dog";

// Step 1
string[] message = pangram.Split(' ');

//Step 2
string[] newMessage = new string[message.Length];

// Step 3
for (int i = 0; i < message.Length; i++)
{
    char[] letters = message[i].ToCharArray();
    Array.Reverse(letters);
    newMessage[i] = new string(letters);
}

//Step 4
string result = String.Join(" ", newMessage);
Console.WriteLine(result);

This code is merely "one possible solution" because you could have taken different approaches to various steps in this process. As long as your output matches the following, you succeeded.
