Solution: Developing a Palindrome Checker

“

(upbeat music) - [Instructor] Let's implement a function that determines if a string is a palindrome. Remember, a palindrome is a word or phrase which reads the same backwards as it does forwards. We'll start by normalizing the input and converting it to lowercase. This will ensure that we treat uppercase and lowercase letters as the same. For our implementation, we'll create a reverse string and check if the reverse string is the same as our input string. We'll use a string builder to create that reverse string. Then we'll iterate through the normalized string backwards, appending each character to our reverse string builder. At the end, we'll convert our reverse string builder to be a string, and then compare it with the normalized string. If the strings are equal, then the original string must be a palindrome. Let's run it. Our implementation works as expected. Now, how can we improve this? Well, instead of manually reversing the string, there are string builder functions and…
