I have been trying to develop a maze generator in Python 3, and I am nearing completion. I have it to the point where I can create the maze as seen in the picture below, however if you look closely, you may be able to see the two issues I am worried about. In some cases, the corners of the path a...

I have integer list with items shown below, Can I please know the logic to move the items to left or right based on given number of steps
List<long> integerList = new List<long>();
[30,40,44,48,23,45,36,87,54,34]
If I have to move left by 3 steps my output should look like

I asked this question a while ago, and since it didn't get much attention I added a bounty. However, when I search by the r tag, there is no featured header, as can be found on stack overflow site when searching a tag:

Calling
List<String> b = new ArrayList<String>(a);
creates a shallow copy of a within b. All elements will exist within b in the exact same order that they were within a (assuming it had an order).
Similarly, calling

We have following endpoint on our api that should grab some events from db, aggregate them and output as a json. But I am having hard time reading this function and hope you could help me out with some ideas how to refactor this to something more reasonable. Or maybe its fine and I just need to r...
I rolled a little container class (just for couriosity) which was meant to be able as a vector replacement in some cases.
(Whoever wonders about the lack of move semantic etc, I just left it out due to lazyness.)

I am trying to implement a fast Inverse Discrete Cosine Transform using divide and conquer method. It is written for 2 dimensional input, but the main part is the 1 dimension transform, which is O(nlog(n)), apply to all columns and all rows sequentially.

This is a basic implementation of the non-cryptographic Xorgens4096 pseudo random number generator with a global, thread safe seeder. The goal is to provide a high quality generator that can be instantiated in multiple threads while still guaranteeing that the seed for each generator is unique. T...
I am new to competitive programming and recently I came across a coding problem on Hackerrank which uses the concept of longest common subsequence problem.Problem link It simply says to find the longest common subsequence of the two given string.

I am working on a python puzzle over at codewars ( Largest Rectangle ) My solution is working for small cases but times out for the very large ones.) I think one major hit to performance is in my subroutine splitz(arr):

I've read some about Object Oriented design and Solid principles. But i don't understand how to implement all these practices to my code.

I'm working on a few C++ language proposals, and it's easier to collaborate with coauthors if we write it in markdown rather than directly in raw HTML. My colleague uses bikeshed to do this translation, but I had a style sheet that I've been working on for a while that I wanted to maintain, so I ...
I'm refactoring a "OptionParser.new do |opts|" block to accommodate over a dozen options and still keep method LOC size to under 10

How can I extract out opts.on statements in to separate methods,
so that def baz is future proof.
