I have a method in a python app to write a list of records to a CSV file. Each record is a "football player", which is really just a dictionary. But one of the dictionary items contains a list of weekly scores. I want to write out to CSV a record for each player, and then flatten the list of s...

You have two eggs, with the lowest number of drops, find the maximum floor of a 100-floor building from which you can drop the egg without it breaking. - I created a function which takes an argument of the floor, and then calculates the answer (since creating the physics engine to actually simul...

Recently I have visited interview. I was asked to write own lock implementation using atomics. Not necessary reentrant. I didn't answer the question but at home I have wrote following code: public class MyLock { AtomicBoolean locked = new AtomicBoolean(false); ThreadLocal<Boolean> th...

Instead of checking whether a local variable is null, then locking when it is, then computing the value, and then on every call still checking if the variable is null and returning the cached value, what do you think of the following pattern (where the value is stored instead as a delegate that r...

I've been teaching myself C for the last few months. As a learning exercise, I set out to write an ncurses implementation of the classic card game Uno, mostly because it was was one of the simpler card games I could think of. Since my emphasis in writing this was primarily learning concepts and...

I've written some code to solve the maximum palindromic substring problem. def memoize(f): """ Function decorator used to cache results """ d = dict() def inner(*args): if args not in d: d[args] = f(*args) return d[args] return inner def max_palindrom...

I'm working on a table football cup program (in C), where I have 16 people facing off to get to the final. I'm having trouble putting elements into the different elements of the array (which has sort of stopped my progress until I figure it out). I've searched on the internet (not extensively) ab...

struct elemMenu { string elem; double prix; }; I would like my program to display as a table all menu items. My program should use a table menu with elements of a type structure elemMenu which contains two components: elem of type string (string header file) and prix of type double. ...

The following code gets video renditions from Brightcove using the media API. It then generates an ordered source list for the JW Player and selects the default rendition based on a pre-set bitrate. JS function buildSourcesFromBrighcoveID(brightcoveID, onComplete) { var sources = []; va...

I recently watched a video course on groovy and started working on some of the Project euler problems to flex my groovy* muscle. (This is problem #8) def number = """ 73167176531330624919225119674426574742355349194934 96983520312774506326239578318016984801869478851843 85861560789112949495459501...

due to an excercise I've written a function that given array of objects and key (2nd argument) returns new array of objects that contain all properties from key. (example input at the bottom of snippet) How'd I do? function where(collection, source) { var arr = []; var keys = Obj...

Once more, I come to you for assistance! I have written a significant bit of code that converts IP Addresses from strings to minimal byte-arrays. (So that you can store them in a binary format instead of as a wasteful string.) It currently works with IPv4 and IPv6 addresses, saving both to a 16-...

This relates to Round to specified int but I'm separating these methods out since they're technically different. Is there a method that already performs a custom floor and ceiling to a specified integer? // If the interval is 5, 9 --> 5. public static int FloorTo(this int value, int interval) {...

I was just wondering if someone could help me make this code simpler? I'm displaying multiple queries and if statements, also in the if statement it increments notice_category_id by 1 each time a category is created but when I code the update/delete/edit (or if truncated) sections won't rowCount(...

This code attempts to create a GUI that has the user input a number and the result is the number in words. I cant seem to figure out how to create it within a GUI. I'm using Java 8 and Eclipse. The only error it's throwing me is in my last 10 lines. enter code here import java.awt.*; import jav...

Cardshifter is an online trading card game, made by a gang of Code Review community members. Cards can have a bunch of different, and sometimes complex effects, and descriptions for these are automatically generated if no custom one is given. EIGHT IMMORTALS: Choose 1 at random: Summon 1 Li...

I've written a templated Cache for storing both active and inactive objects. If an object were to be "removed", then it is simply moved to a queue of inactive objects. The vector of active objects will never be searched, only accessed. So I have no problem with there being holes in the vector. ...

Creating a simple blackjack game that only uses loops(no arrays) that allows you to input how much money you want to bet, calculate the value of your hand and give option to hit or stay against dealer, and output whether or not you win. I am a first year programmer with about 6 weeks of experienc...
