While a fair intro to arrays I personally feel there is a number of problems:\n\n* The target audience is unclear: the intro talks about arrays as if the audience has never used a programming language before. Surely that\'s not what leetcoders are? Then later sections miss out a lot of topics, that I would personally like to hear about.\n* Questions put after each section are often using concepts that haven\'t been mentioned at all, a big theme here is the "Two Pointer" trick and many require in-place operations before the "in-place" section has even been reached\n* One question that is set up to be solved by creating a new array, follows the first "In-Place" section... \n* The focus is a very much on Java, this wouldn\'t be much of a problem but a lot of characteristic\'s of Java\'s arrays don\'t apply to Python (which seems like a much more popular interview language)\n\nIn general this makes it quite frustrating. The descriptions could definitely be reworded to be more encouraging as well.
