I'm attempting to solve the "Missing Numbers" challenge on HackerRank where I'm tasked with finding missing elements comparing two arrays.
Foundation's NSCountedSet is a little pokey on large data sets, I rolled my counted set with a Swift Dictionary. I'm able to pass all the test cases with the...
Can I improve this code to reduce the number of loops?

So, I am either a glutton for punishment, or I have no life, but I wrote a script to answer a question over on Ask Ubuntu as a solution for selecting a random MP3 file in a given directory, and playing it in the specified player of choice. I am half-embarrassed to share this because I know it's ...
I am writing a small program that is supposed to act as a shell of some sorts. It operates off of a few basic structures, one of them being a command, a command_list, and a command_history.

char** list;
int len;
} command_history;

I've written code that solves a problem from codewars.com. My code passes all the tests on the codewars site. It's a simple enough problem to solve naïvely, but I would love to improve the structure.
The prompt for the problem is as follows:
Write a function, persistence, that takes in a pos...
I'm having trouble with looping my program so that it breaks out of the loop if user enters "quit" or "exit".
When I type quit or exit or any string for that matter, my program crashes as it tries to parse the string input to an int. Any advice?

I have some code which generates the coordinates of a cylindrically-symmetric surface, with coordinates given as (r, theta, phi). At the moment, I generate the coordinates of one phi slice, and store that in a 2xN array (for N bins), and then in a for loop I copy this array for each value of phi...
When I read this answer, which has code:
linqObject.Where((obj, index) => {
DoWork(obj, index);
return true;
}).ToArray(); //MUST CALL ToArray() or ToList() or something to execute the lazy query, or the loop won't actually execute
My initial reaction was similar to Mark Sowul's comment:

This is A:
if ($keyword instanceof Post) {
$mltQuery->setLikeText($keyword->getTitle());
} elseif (strlen($keyword) > 0) {
$mltQuery->setLikeText($keyword);
} else {
$mltQuery->setLikeText('DEFAULT');
}
This is B:

I came across this trivial dilemma (a oxymoron for you).
1.
if(exampleArray.length > 1) {
for(int i = 0;i < exampleArray.length ;i++){}
}
2.
for(int i = 0;i < exampleArray.length && exampleArray.length > 1;i++){}
Which is more good taste programming?
I would say 1 is more efficient and 2...

I've written an Android app using Android Studio that, when the main switch is enabled, toggling other switches or pressing a radio button calls a certain script.
I'm familiar with Java itself, but I'm very new to Android development. What could I do to make this code less messy? It works fine, ...

I need to sort a large array (5 columns x ~500,000 rows) of string variables by two columns. I have code that works, but it takes an unacceptably long time. Particularly because I have to do this on five sheets with different data.
