Some minor improvements:
In insertionSort() and bubbleSort(), I don't use the already written swap() method. Instead, I do:
temp = toSort[j];
toSort[j] = toSort[j - 1];
toSort[j - 1] = temp;
In bubbleSort(), my code will still iterate over the remaining elements even if the array ...
Write a program that prompts the user to enter two
arrays of integers and displays the
common elements that appear in both arrays. Note th
at the first number in the input indicates
the number of the elements in the list. This number
is not part of the list.
I have an AngularJS function that is used to determine which $scope associative array variable is to have data pushed into it. I would love to be able to remove the switch case entirely if possible but haven't been able to envision a way to do that! My overall goal is to both improve performance,...
I built an app where a user has a recipe box with recipes in it - for the db, there is a user and recipe model, user has "recipeBox" property. The recipebox is an array of objects like so:
User model....
User.recipeBox = {
["id1", "done": false],
["id1", "done": true],
}
The done property is...

First of all, i will admit that this is a university project.
I am not sure whether that is allowed or not. Also admit that i am a massive beginner who is a novice among novices. So please excuse some extremely nuts blunders i might have made.

I have made the bold claim that a longstanding problem in Rebol is "now solved"...that of "definitional returns".
But of course, such claims need some peer review, and there's always some new trick to learn or improvement to make. So I thought I'd paste some code here. Even though it doesn't...
I was asked to create an email contact form as part of an assessment. The instructions were:
Take in details from three text inputs (first name, last name and
email address), compile an email and send it to mytest@thistest.com
If a check box is ticked send the details to a database table cal...
I've recently taken a renewed interest in non-standard languages like Brainfuck and TIS-100. I'm currently writing a Fibonacci generator in Brainfuck which differs a bit in approach from the usual generators already around.
Since my current understanding of the language is very limited, the limi...

I'm working on a small application that uses a WebService to get meta-data about television episodes. What I'd like to do is start building out a local cache of the series so that I can reduce the number of calls to the service. Data being stale is not a concern at all for this case. I've chos...
I am developing a service where the user need to sign the seller agreement with Mobile BankID (Swedish e-sign service). To make this work I need to make SOAP request to get the progress status of the signing request in Mobile BankID.
Is this code understandable? How can I make it more clean?

I have tried to implement the "DFS" algorithm to find all the back-edges in a graph that lead to a cycle in the graph.

I was bored, so I wrote something that could turn wav files in to bmp's.
#include <stdio.h>
char bmp[12000029]; // Need 12000028 bits, 1 pixel is 3
// bits and table is 28 (1500^2 * 3 + 28)

I'm attempting to make a builder pattern that makes sense and is practical for storing user data in a flexible way in a document database. The DB I chose is MongoDB, and I'm using its Java API throughout. I plan on replicating this kind of pattern once I have something that is decent. This works,...
The jaccard distance between two sets is the length of their intersection divided by the length of their union. For example, the distance between {1, 2, 3} and {2, 3, 4} is 2 ({2,3}) / 4 ({1,2,3,4}) = 0.5.
The Jaccard distance can be used for string similarity by slicing a string into word or c...
This is a follow up question. I am trying to design a thread safe parameters class with only readable getters. Please find below. I am interested if this is thread safe or not. This is my real code.

I wanted to write a JavaScript function that checked for balanced braces. I'd be grateful for any feedback on correctness and style.
var invert = {
'}': '{',
']': '[',
')': '(',
};

* `false` otherwise.
* Usage: `matched('{{[(')`

I wrote this program, and it does what it asks, but it's so big and ugly. What can I change?
Some examples:
a b c --->
5 1 12 a is between b and c
5 12 1 a is between c and b
5 5 2 there is no gap
This was in an example of a test that is supposed to be small, so that's why ...
This challenge challenges you to write a function that will take as its argument an array that specifies the types of input, an optional prompt, and a verification key; inputs and validates the values; and returns them.
Input types:
b - Boolean values.
c - Characters.
i - Integer values,...Recently, I submitted a project that simulates a barbershop-style problem; the task was to create a "Hotel" that contained guests, front-desk employees, and bellhops. Each of these were to be implemented with their respective Semaphores, with mutual exclusion being kept to a minimum if possible.
