I was curious on how I could create a random string and have it have a set prefix. Lets say, as an example, 3456. This question is more referring to how I would join two strings together, my prefix and my random string. To give a more comprehensive exmaple of what i'm looking for, let's say I g...

I wrote this code to simply visualise what happens to an image when it gets put through repeated convolutional filters is a CNN. The code works fine and produces the expected result but the it is also very inefficient. One thing I can't figure out is when we want to apply convolutional filters to...

I know this has been done many times before, but this is my existing code taken from a sample I found to async process a list of tasks. I've seen Task.Run in use before in many examples, but I'm assuming that in most cases, the workload will be IO bound and therefore the Task scheduler is not cle...

Related: Find all distinct subsets that sum to a given number This code is supposed to efficiently generate all subsets of a list such that the subset's values sum to a particular target value. For example, given the input list [5, 3, 2, 1] and the target 8, it should produce [5, 3] and [5, 2, 1]...

My code does a DFS on the given graph and prints all possible paths for a given start and end node. My question is how can this be improved? Can some form of memoization be used here? There are cases where a path from a certain source - destination is already found and will be an intermediate pa...

I currently I have this code if (this.showAllOnlineFriends === false) { this.showAllOnlineFriends = true; } else { this.showAllOnlineFriends = true; } When you press a button, it will toggle a boolean on or off. Is there a more readable way to write this?

Recently I had to do an IKM C++ assessment to qualify for a job. Some of the questions seemed strange to me, so I'll be doing a few posts here to discuss. The first one is related to use of std::unordered_set. From what I remember it went something like: A programmer is using a struct to contain...

I found this code online and it works good for hiding one folder, but I would like to tweak it to hide multiple folders at once. Any suggestions? @Echo Off Set Input=%2 If %Input%' NEQ ' GoTo Main Set Input="folder location" GoTo Main :Main If Exist %Input%\nul ( Dir /B/Ad-h %Input% ) ELSE ( Dir...

IntelliJ warns me that I should avoid using return. If sender is empty, the function should not continue parsing the bytes. The return value of keyType() is an Option. What is a better way to return Left in case of an error, without using a return statement? object TransactionV3 { private val l...

I only wish to make it more efficient, and I doubt it's at max efficiency as it is. So here it is. """ This code runs a hangman game for the user.
