I'm going through the artificial intelligence domain at HackerRank. I'm very new to this domain and I really need a guide on how should I minimize the number of if/else statements in my code.
Problem Statement
The goal of Artificial Intelligence is to create a rational agent
(Artificial In...
I am developing a library to easily register wordpress custom post types and taxonomies.
but the problem is i can't use one instance of object because of adding the object in wordpress hooks.
so what i have done as solution to re instantiate the class every time when you want to register a cust...
I want to be able to initialize and add elements to a custom container from other common containers
Instead of handling each container separably, a really simple solution would be to create a template method that grabs the iterator from any container passed as argument.
Like this:

Going through the google foobar challenges. Currently on the first challenge of level three. I've come up with a working solution, however, it's not an acceptable solution because it runs out of time. How can I optimize it?
Problem Statement
Oh no! The mad Professor Boolean has trapped Beta Rab...
I want a regex that matches any 0,X slice of a given string - so for the string "test", it matches "", "t", "te", "tes", and "test". I have a few solutions, both so inelegant that I've taken to programmatically generating them - not ideal.
Solution 1:
(?:t(?:e(?:st?)?)?)?
Solution 2:
(?:|t...
Two strings are isomorphic if the characters in s can be replaced to get t.
Can efficiency be increased further for the below code . As am getting errors that limit is being exceeded for very large strings.
static boolean isIsomorphic(String s, String t) {
s= s.toLowerCase();
t = t.toLowerCase(...
Are we allowed to ask questions just about regular expressions?
I have a simple calendar program. Dates and notes are saved in database(first cell is Date and second is Note). All noted days have bolded font in calendar.
But When I run program again all days have no-bolded font, no matter was it noted or not.
How can I fix this ?
I tried to make something li...
On my web forms page, I have this huge GridView. I make it refresh every five minutes since the data has to be up to date.
It has sort options, so upon every refresh, I use cookies through every refresh to remember the search and sort options.
In the Page_Load function, this is how I do it.

I am running a piece of cloud code:
Parse.Cloud.afterSave("CustomMessage", function(request, response) {
// Notify
var query = new Parse.Query(Parse.Installation);
query.equalTo('user', request.object.get('toUser'));
Parse.Push.send({
'where': query,
'dat...
Grade 0: ++
This is so low that it is boring; the operation of grade 0 is incrementing or counting up, for example:
5++ -> 6
8++ -> 9
Grade 1: +
Addition is repeated incrementing:
4 + 3 -> 4++ ++ ++ -> 7
2 + 2 -> 2++ ++ -> 4
Grade 2: *
Multiplication is repeated addition:
3 * 4 -> 3 + 3...
I have a very problematic nested if/else/for that I'm sure it could use some love. Here's how it looks originally:
function addBookmark(obj) {
var isFound = false;
var posFound;
if (bookmarks.length > 0) {
for (var j = 0; j < bookmarks.length; j++) {
if (obj.mirro...
Questions seeking an explanation of someone else's code are also off-topic.
This part of the shown close reason has a link on "someone else's code" which leads to this meta answer: http://meta.codereview.stackexchange.com/a/3654/29371
which clearly states how this is meant
For mor...
You've posted a lot of code, so I'm going to give a general overview of some common mistakes I see people making (and are also happening here).
You are using lots of magic numbers and magic strings. Let's instead create constants somewhere for all of these.
You're using NSLog statements withou...
I have a method that basically passes in a known drawn line segment in my view and then draws parallel lines n distances away from the passed in original line. This one in particular draws two parallel lines on either side.
I am wondering, it seems to be a lot of repeat code here, how can I ref...
Graduated sites may have up to five standard off-topic reasons. Why are beta sites are limited to three?
Is it because "you ain't going to need it"? That is demonstrably false for Code Review — we have struggled to collapse our off-topic reasons into three categories. And that is confusing fo...
Inspired a bit by a previous Brainfuck question and the recent fizzbuzz invasion, I decided to make FizzBuzz in Brainfuck.
The code is entirely my own, except for the inclusion of the Printing a number algorithm that I found on StackOverflow.
My code is divided into several parts.
Setup Const...
For a class, I need to ask the user for a double. To verify that the number can be safely passed to Double.parseDouble, I wrote the following function. I'd like to have it heavily scrutinized; including the comments.
Are my comments helpful? They're more directed towards the marker than a maint...
