Time for action – revisiting the palindrome problem

With the two methods, Reverse() and EqualCollections(), finding whether a sequence is palindromic or not becomes a single line of code. Let's see how:

1. Copy the following code in LINQPad:

   string word = "rotor";
   bool isPalindrome = 
   Algorithms.EqualCollections(word.ToCharArray(), Algorithms.Reverse(word.ToCharArray()));
   string status = word + " is ";
   if (isPalindrome)
       status += "Palindromic";
   else
       status += "Not Palindromic";
   status.Dump();

2. Run the query. It will generate the following output:
   

This method can work with any type of collection.
