I’ve done this kind of input-validation and search task a lot in school, so the logic is familiar — but I was wondering if there’s a shorter or more elegant way to do this. It works, but the repeated validation and re-prompting feels a bit verbose. Would love to save time during exams if I could streamline things like this.
I am just interested.
