This is a follow up: Optimization over 7 constants, running a function 10,000,000 times And my data can be downloaded at: http://we.tl/J0qBfgnPUY Thanks to a very helpful post by Joshua Ulrich, the function percentcorrect function is now running much, much faster. The only kink left is the bet...

Initially I had my configuration data (db credentials, cookie expiry time..) in a GLOBALS variable, which I know is not a good idea. So now it is in a ConfigManager class which handles this information: <?php class ConfigManager { private $config; function __construct() { $this->...

A while back I made a custom String struct (see github repo) because of the difficulties in dealing with Mongolian Unicode rendering when using Swift String or NSString (see this question and the accepted answer for more details). The struct is an array of UInt32 so that it represents a string of...

Time complexity is supposed to be: O(n * log n) // Copyright [2015] <none> #include <cstdlib> #include <cstddef> #include <cassert> #include <iostream> #include <vector> #include <iterator> #include <utility> #include <numeric> #include <random> #include <algorithm> #include <limits> // #define...

I've written a function which, given a number string, returns the next largest palindrome in string form. For example, if the input string is "4738", the output should be "4774". The original problem description is found here. The function seems to be working for all the tests I have thrown at i...

This seems to work, but for some reason I'm not entirely sure about it. Can anyone point out any issues with this simple pub/sub library? Thank you! (function (undefined) { window.mylib = $.extend(window.mylib, (function () { var subscriptionsBag = function() { var se...

I am very new to programming (using C++) and coded a sudoku solver as a weekend challenge. I guess there are so many things to criticize, but I would really appreciate some constructive criticism. Just what strikes you the most. If you want to run the code, a "sudoku.txt" has to be in the same di...

I am training a colleague who is familiar with Python but has a limited knowledge of C# and complexity. I thought the following problem could be a good start.
