Problem
Check if an input string is a palindrome {is the same if reversed}
Solve
Step 1. The Method
Reverse the input string {as a StringBuilder}. Compare the reversed string to the original. If they're the same, that's a palindrome. This is an easy to write solution. Though given its nature, it's not the fastest implementation! A quicker way would be to compare characters at either end, moving towards the centre.
