The below is to parse a lisp expression (doing as much as possible in 'one go'). How does it look, and what can be improved?
# goal: capture the next token then get the rest of the line
# to be used in a while-loop/yield

I am trying to solve this leetcode problem. Even though I solved it, I would like to see how I could translate my Java code to Python, since I am learning the language and its OOP components. How would the translated code look like?
This is the solution:

A common preprocessing in machine learning consists in replacing rare values in the data by a label stating "rare". So that subsequent learning algorithms will not try to generalize a value with few occurences.
Pipelines enable to describe a sequence of preprocessing and learning algorithms to en...
I wanted my code to do the following in a list: when the index is bigger than 0, duplicate to its value. So for example:
ListOp :: [Int] -> [Int]
ListOp [1, 3, 2] = [1, 3, 3, 3, 2, 2]
ListOp [ 5, 0, 1] = [5, 5, 5, 5, 5, 1]
ListOp [ 3, -2, 1] = [3, 3, 3 , 1]
I was wondering how to improve my code...
I made a Rock Paper Scissors game. It works fine but I would like to know how can I improve it further.

I am building a library to abstract DOM manipulation. Here's what the usage looks like:
vsAddToSection() {
let _inChapter: c.InChapter;
let v$sections = vmap([], _ =>
vh('div.section.item', {}, {
listeners: {
click: (e, __) => {

I just learned about arraylists and I got a mission to build Mobile phone application with contact list when you can add \ remove \ modify \ search for contacts.
I would like to get a review!
if you think I should add something to the code feel free to tell me :)
thank you!

I work in Rcpp and wrote the following code:
#include <RcppArmadilloExtensions/sample.h>
// [[Rcpp::export]]
int NonDiagSum(arma::mat n, int K){
int sum = 0;
for(int i=0; i<(K+1); ++i){
sum += n(i,K-i);
}

I tried implementing a thread-safe ring queue in C++. I'm totally new to move semantics and C++11/14/17 in general.

Hi I want to ask question about a better way for implementing single endpoint rest.
I want to build a rest API but I want it to only have single endpoint like: graphql, where you only have like: host/graphql.

For a project, I need to make use of Selenium WebDrivers, and since they're so expensive to start, I decided to write a pool to manage them.
with driver_pool.FirefoxWebDriverPool(5) as d_pool:
# Sequentially visit a page 1000 times
for _ in range(1000):
# Don't actually run this. ...
Learning Modern C++ patterns and this ended up being the direction I went to to create an encapsulation of SDL's window management, while trying to stay with RAII practices. This is meant to be a base for a software renderer (and possibly expanding to OpenGL after that).

I recently developed code that can run as a function parameter but I'm not quite sure how vulnerable it is to hacks and/or cheats. Also, is there anything I could improve? Thanks
