Recently, I came across a request to reverse a given string in Java. This does seem a bit odd, but nonetheless, I was asked to perform a reverse without using in-built methods, additional parameters, or any other common way. I am not sure if other companies follow this trend of not using Java API methods, but still, in interviews, companies want you to think beyond what you know and would typically do.
