I needed a way to normalize nearly any given input for a configuration parameter on a dashboard. Server side code is in php so i wrote a test script to experiment with preg_replace and regex. When I say normalize meaning, the resulting value must match the following restrictions: Take any cas...

The goal of this is just to practice. I went off on a self-challenge to replicate something(So the names of the parts can be ignored), I'm not done yet (Though what is here is fully runnable), but have enough code that I thought it could merit taking a moment to examine whether I could be doing a...

I'm making an experiment on JS, trying to build a framework for OOP. It's called Universe. The main purpose is to emulate a mini-universe, where classes are created with a defined behavior (prototype) and objects are created from those classes to provide data. So far I managed to make inheritan...

Please see this question for the general description. Exercise 2: localMaxima :: [Integer] -> [Integer] A local maximum of a list is an element of the list which is strictly greater than both the elements immediately before and after it localMaxima :: [Integer] -> [Integer] localMaxima l = ...

I've been trying to solve this problem on Codeforces: http://codeforces.com/contest/525/problem/A but I keep exceeding time limit on one of the test cases. I made several changes (i.e. using try/except instead of 'if a in b') to my program but it still can't pass that test. My last version is t...

Please see here for the general description. Exercise 3: histogram :: [Integer] -> String takes as input a list of Integers between 0 and 9 (inclusive), and outputs a vertical histogram showing how many of each number were in the input list. histogram :: [Integer] -> String histogram xs = le...

I've got an object $contest which is a Symfony entity that has some other entities assigned. I can get them by $content->getEntries();. That will return an object with the lazyloaded db objects. I need to display them in a random order. $tempEntries = $contest->getEntries(); $entries = array(); ...

I have implemented a basic high score server for my strategy game. The goal here was to get the high scores working for the browser based version of the game (I am using the libGDX library with GWT for this version). Unfortunately this required using websockets, which made the process more diff...

I've just finished (well, I can't find any more ways to break it so I guess that counts) a small function that will reduce the size of code as much as possible without breaking anything.Obviously it makes everything a bit unreadable so it's not really for cleaning the code, more for if you want t...

can someone tell me how good/bad this code is for a super simple todo list made from vanilla javascript? Anything to work on or consider on my next projects? Thanks so much in advance! // establish variables var addButton = document.getElementById('btnAdd'); // event listeners addButton.addEven...

I wrote this code to form combinations of a 16 bit binary number (I know it is in output is string format, but it is my goal to just print all possible 16 bit binary numbers). My question is, can this code be optimized? How can I calculate the time complexity of this code? public class Combinati...

Recently, I have been working on a pong game in python using pygame. I have a complete basic game, however there are two problems. 1) The ball always follows the same trajectory and I do not know how to fix this 2) The AI is set to mirror the ball's motion. However, as a result, the AI always mis...
