If you put ABcd in quotation marks, then it makes sense. You can search the JDK documentation to understand how the standard library works. https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/String.html The number argument, is the begin index.

Mustakim Rahman In Challenge question doesn't make sense of copy paste instead there should be explanation but as challenge questions were posted by community member so I think that is why not available. For the image in QA you can do one thing take screenshot, upload image in post and then share the post link with question.

Mustakim Rahman you can send your suggestions to [email protected] or use the feedback menu in the mobile app. They most likely won't read this forum.

In challenge part developers should add copy-paste option so that users can easily copy those code which they don't understand.
