Is this an efficient way of finding the minimum using binary search?
//Find the minimum in a sorted rotated list of numbers
function findmin(arr, low, high){
if(low==high)
return arr[low];
if(arr[low]<arr[high])
return arr[low];
if((high-low) == 1)
return Math.min(arr[high], ...
I am developing a 2048 program in Python. As a part of that project, I am working on merging method that merges the given integer entries.
I am interested in some suggestion to improve my code.

What is a Zombie? Why are Code Reviewers so violent and talking about killing Zombies all the time? And what ammo are they talking about? What is a TS? What does RSA mean?
And what other Code Review-specific memes are there?

How works and what does that actually mean?
How can a post be deleted?
How can I undelete one of my posts?

I read user input from stdin in plain C.
The problem is that I want a sane implementation that is robust to errors and restricts the user to a certain input and doesn't suck in terms of complexity.
The function get_strings() reads input char by char as long there is no new line (\n), no EOF and...
Today I saw a user in a per site meta that has a reputation tab like this:
Their meta post is about something else though. The problem I have is with this very screenshot:
4 un-upvotes took place in a range of 5 minutes
For the sake of a consensus, I'm not asking for someone to look into t...
I have been going back and forth on one certain part of my code. It works, but it doesn't seem right for some reason, as I believe there must be an easier/cleaner way to implement the NSUSER DEFAULTS. All of which are dates. I apologize that the code is so long. A lot of it is repetitive, and I w...
The following code implements a Skip List based on "Skip Lists: A Probabilistic Alternative to Balanced Trees" by W.Pugh.

NO!
There's a reason that Apple didn't bring #define pre-processor macros into the Swift language. Generally speaking, the primary function of these macros is to make debugging more difficult.
In almost all cases of macros, you can...
According to balpha, the SE chat sites may have individual Easter eggs, depending on the site. If you find them, please post.
Edit:
Because it's so easy to make this stuff up, a screenshot as proof would be nice. (Although Photoshop ain't that hard either...)
Find the first row in the matrix with all positive elements, and the sum of these elements. Zoom all the elements to this sum.
Here is my attempt, but this way sum the positive elements:
matrix = [[-5, -6, 2], [7, 2, 3], [8, 4, -9]]
summ = 0
for i in range(len(matrix)):
pos = False

i just finished my first game-porting to cocos2d-js and i am now in the process of code-optimizing.
Since I come from a Object-Oriented Background i usually put all my game Logic in an extended cc.Class like so:

ctor:function(gamelayer,overlaylayer) {

Based on the previous question, I have implemented all suggestions. Also, I worked a bit in this project to improve it.
Summary of improvements:
split the code into multiple files as .hpp and .cpp
removed STL functions
used only one sf::RectangleShape for border instead of std::vector.

I came across this interesting question while reading 'Cracking the coding Interview' and came up with a simple implementation. Any suggestions are welcomed.
Imagine a (literal) stack of plates. If the stack gets too high, it might topple.
Therefore, in real life, we would likely start a ne...
The Ford-Johnson algorithm, also known as merge-insertion sort (the name was probably given by Knuth) is a in-place sorting algorithm designed to perform as few comparisons as possible to sort a collection. Unfortunately, the algorithm needs some specific data structures to keep track of the orde...
I have a ExportDialog with ProgressBar Stop and Break buttons, which uploads some data.
I use QThread and everything goes OK but sometimes MainWindow, from where ExportDialog was run gets frozen (grey) and I can't click Stop and Break, only exit. Also, I have some values, which get changed and s...
when i press a start button then update database column value everyday and when i press stop button then database value can not update. how i solve this by asp.net using c sharp from code behind without loading page. Database value will update automatically .
A while ago I was experiencing 'flakiness' on my home ADSL line. I run a Linux server in my basement, VOIP, and a few other things (like Netflix) and I was experiencing a few minutes of network downtime every few hours. This was dropping very important things, like the kids watching cartoons, and...

So I’m a physicist, and the attempt here is to scan a simple text file of the format

to find the line with the first entry equaling that of run and to consequently assign the parameters A[i] of that line and then exit the loop. This is a trivi...
While working on a small project, I tried to implement a super simple tree class in C++. It supports an arbitrary number of branches from each node.
In addition to general comments, my main concerns are:
Are there other common tree functions that should be implemented? (So far I know about t...
