I have an exam in Algorithm Design and Analysis coming up in the first week on July, and have been practicing implementing a number of the algorithm design questions in past papers. They are usually obscure questions around some sort of bin packing or placement. I attempted to implement this question described in the Gist using JavaScript and would like to get some feedback on my attempt. Thanks!
