I am attempting to optimize a piece of C code which aims to multiply a series of pairs of unsigned shorts and add the result. I am only concerned about the high 16 bits of the result, and I can guarantee that the sum of the multiples will fit in a 32-bit value. I initially coded this in C, and then rewrote it to use SS... |
I was experimenting with lists, sets, and finally maps when I spotted a pattern in my code to make it recursive. Now I haven't used recursion much in the past or at work and I was very excited to have something that does recursion.
I have this recursive method that takes in an Integer and returns a string representatio... |
I decided to put together a quick project using jquery, the Kendo UI HTML 5 framework and JavaScript.
I don't do much JavaScript development and I'd like some input on how to make this look less like a complete spaghetti hack, walking up and down DOM elements, trying to find the right event handler to hook onto.

I'm learning java, although because of work I didn't had much time to go to classes. We had a final work to do but since I'm more familiarised with python I'm not sure if I'm doing java correctly...
I'm also a bit confused about attributes and constructors, I don't really understand the use of it.
For this work we have... |

$(document).ready(function() {
introIconFirst();
function introIconFirst() {
$('h2.ribbon').css({
'marginTop': '+30px',
'opacity': '0'

Here, I am trying to run 4 operations in parallel and it worked great. Here is the complete code:
public class SampleController : AsyncController {

First number indicates the number of points, followed by N points
(x,y). Then the next number indicates Q num_queries, followed by Q queries:
Reflect all points between point i and j both including along the
X axis. This query is represented as "X i j"
Reflect all points between point i and j both including alo... |
I'm calling this function from my html (and in some cases from another function in my JavaScript). These type of switch statements are starting to litter my code. Is there a more elegant solution to these if statements? I wish I could pass a reference to the variables I want to modify. I'm finally asking the questi... |
I would like to simplify to following function as much as possible:
public string[] GetPowerSet(string input)
{
IEnumerable<IEnumerable<string>> seed = new List<IEnumerable<string>>() { Enumerable.Empty<string>() };
return input.Split(',').ToList().Aggregate(seed, (a, b) =>
a.Concat(a.Sel... |
