nyxxx, you're wrong, I'm sure you're deliberately answering it wrong. For example, in the question "Given a Text type input of ri!text, which function will return that text without any spaces in the text?" you have claimed things that anyone who has read the documentation knows is a lie, and you have claimed that "according to the documentation..." when you have not. So constantly, whenever there are at least 2 posts in the discussion I know that one is going to be yours and that you are going to make up the documentation as you please. There are several answers to questions that are wrong among the whole battery of questions, but you miss the ones that are impossible to miss. I don't know if you work for Appian or what, but stop confusing people on purpose.
