I'm working with Sqlite and I'm trying to find out how to modify a table to add a new column and fill those values using a LEFT JOIN
So, consider the original table is R and the table that I want to LEFT JOIN is T. The shared column between R and T is C; and the column from T that I want to add t...

U can sort their game list by their release date, however there are just too many games. In their website, there's an option called "Popular only", which only shows games that are being followed by at least 1 people.

So I came across this question on SO and I felt like it would be a cool thing to try and write a parser for since I always wanted to try it. So I present to you:
My first time writing a parser.
It converts strings like this:
"a,s,[c,f],[f,t], [[a,c],[d3,32]]"
into list objects
['a', 's', ['c', '...
I needed to dynamically load and instantiate some classes from a generated jar and a generated .class file which depends on that jar. So I came up with this:

Unity scripts need access to components they will be using, my solution here guarantees that a script will have a valid reference to a component it needs, but is this solution overkill, or hard to discern intention from?
Note: null coalescence operators would be cleaner but cannot be used for uni...

The goal here is to pull all alerts from a single iterable:
obj = Alerts(db, args)
for alert in obj.alerts()
pass
Now, I need to add a few more sources and I'm not sure if this is a good approach to instantiate all classes in the AllAlerts constructor? I also don't like the fact that I'll ha...I need help in rewriting my code to be less repetitive. I am used to coding procedural and not object-oriented. My scala program is for Databricks.

I created a solution for the car pooling algorithm.
Problem:
You are driving a vehicle that has capacity empty seats initially available for passengers. The vehicle only drives east (ie. it cannot turn around and drive west.)
Given a list of trips, trip[i] = [num_passengers, start_location, end_...

Here is my algorithm

The following joke is popular:
An MIT linguistics professor was lecturing his class the other day. “In English,” he said, “a double negative forms a positive. However, in some languages, such as Russian, a double negative remains a negative. But there isn’t a single language, not one, in which a...

I wanted to know how "dark" each character is when printed. I thought that this may be useful when doing ASCII-art to help with shading. I decided to write a program to objectively measure how much coverage of an area each character provides, which should roughly translate to how dark it appears ...
