In this code i have used tail recursive which is bad and time complexity is still O(N^2) which is worse case. only good part is memory complexity.
How to improve recursive part of this code?

The game is cheatable.
Like most software, the game is cheatable whenever there is a debugger available.
In this case, I have loaded up FireBug in Firefox, and learned a few tricks. Here's how the game is cheatable.
Note, this is based on playing the game from your source here:

I'm trying to learn how to use makefiles, and this is my attempt at making a makefile that compiles source files in a source directory (src/) into object files that are created in a bin directory.

let's say we have a CountryList object in our application that should return the list of countries. The loading of countries is a heavy operation, so the list should be cached.
Additional requirements:
CountryList should be thread-safe
CountryList should load lazy (only on demand)
CountryList...

I was recently given this programming challenge on an interview, and I decided to use javascript to solve it. I did, but I'm not happy with my implementation. I can't help thinking there must be a better way of doing this.
The exercise goes like this:
Given an array of integers, write a funct...
I got thousands of files with a specific file extension in thousands of sub folders. Now, what is the fastest way to search with a pattern? I tried the method DirectoryInfo.GetFiles(rootfolder) (~8 Minutes) and a recursive custom method (~5 Minutes).

I was eager to learn the implementation details behind windowing GUI systems. Because I am mostly a high level programmer having no much experience in low-level stuff, I had to simulate it instead of implementing the actual one such as Windows Explorer, KDE, Gnome, X11 and Mac OSX Aqua.
There is...

Your code does can't escape this loop, unless you are hitting STRG + C

I'm really inexperienced with cycles, so I want to make this code shorter. As far as I know, I've made a recursive cycle.
for (Pointers[0] = 0; Pointers[0] < 8; Pointers[0]++)
if (AdjM[Pointers[0], VertStart + 0])
{
for (Pointers[1] = 0; Pointers[1] < 8; Pointers[1]++)

This might be difficult for me to describe clearly but I will try anyway. Also note that this is entirely speculative; it might not even be able to run any faster (that is why I am asking).
So this is a question directed at performance. I have been trying to improve the performance of a method ...
I have a WCF duplex service that is using the WSDualHttpBinding. It is set to use custom username/password authentication via a UserNamePasswordValidator. The service works fine and never generates any errors.
The problem is that I am able to connect to it without any authentication. This tells...
I'll answer your second question first! The fact that one of your your checkboxes needs to be checked is a validation that is more about your class than one of your checkbox. I mean, individually, a checkbox doesn't need to be checked, but your model requires one of them to be. Which is why I wou...
