I'm working on a small final fantasy type game. I have this for a tile map. I was just wondering if this is a good way to do this or if anyone has any suggestions, I would love to read them.

I tried to tackle #17 problem on project euler:
If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total.
If all the numbers from 1 to 1000 (one thousand) inclusive were written out in words, how many letters w...
I finally converted my horrific HTML regex parsing:

In my data structures and algorithms class, we were introduced to the splay tree, a BST with the additional property that recently accessed elements are quick to access (because they stay at the top of the tree until a different element is accessed).
I know that std::map uses a BST; I heard it's...

I have a "cumulative" lookup array for a custom collection view layout.
The idea is that I have an array of rectangles, each with an index. The index is not unique. I need to create a lookup table, such that given a cell index, it returns the accumulated height of all rects lower than that inde...
Here is the code :

for(j=0;j<4;j++)

To make a point in another topic, here's one take of the 'simplest possible sieve' that can sieve up to 2^64; the idea being to make things so brutally simple that we can trust the thing to be right and can use it to verify other, more complicated implementations.
The code here works perfectly f...
A while back I was asked the following question in a phone interview, and to be honest it stumped me. After many long nights of rolling the problem around in my head I think I came up with a decent solution
The Question:

[(5, 7), (11, 116), (3, 6), (10, 1...
Let's say that I have the following code:
String word1 = "bar";
String word2 = "foo";
String story = "Once upon a time, there was a foo and a bar."
story = story.replace("foo", word1);
story = story.replace("bar", word2);
After this code runs, the value of story will be "Once upon a time, ther...
this is my first question here, I was not sure if it's more appropriate here or in the stackoverflow area.
My code works fine, I would like to know if I chose the best strategy to implement my code, or if It can written better (more fast, more clear, best use of design pattern, etc).
In my andr...
I have got an array with object where each object contains information about school and business area like this:

Reffering other "Stack Exchange" Sources, I've been told that the only way of swapping BGR to RGB involves buffering. While this isn't true, I could just perofrm a quick C-SA algorithm on fseek or bmp buffer byte offsets. I wrote a fast implementation of fwrite, that swaps the first byte with the...

The typeof() macro allows a few things.
First of all, personally, I've created a code snippet with this sort of thing. Instead of having to type out:

each and every time I want to set this up, substituting MyClass for the appropriate class, I can instead just...
The JSON standard uses double quotes for key names and string values, such as the following:
{"one":1,"two":"two"}
However, the current project I am working on requires JSON-encoded objects to use single quotes instead of double quotes. (In this case {'one':1,'two':'two'}). Right now, there is...
