The question is: Given an array of integers say [8,4,6,12,10] You can pop any two elements at a time and place the sum back into the array. Repeating until a single element (final sum) is remaining. What is minimum final sum, given that you are allowed to pop any two elements at a time? My ap...

I have a command exec metod that blocks UI and I just wanted it not to do it, so I wrapped method call with Task.Run. Note, that GetParsedHorseData is CPU work, not IO. /// <summary> /// on `Find` horse btn click, /// on `AutoComplete` of the horse name / jockey TextBoxes, ...

This problem is from Automate The Boring Stuff using Python - Chapter 7. Write a function that takes a string and does the same thing as the strip() string method. If no other arguments are passed other than the string to strip, then whitespace characters will be removed from the beginnin...

This is on a resource constrained environment, so ideally everything will be statically initialized. Can't use new. It sort of looks readable like this: State states[] = { State(Off) .with(Transition().on(Dark).to(On)) .onEnter([]() { printf("Switch off"); }), State(On) ....

Is there anything missing or any pitfall when using BigInt? // Assuming n is an integer and is 0 or greater function factorial(n) { var i, result = BigInt(1); for (i = BigInt(2); i <= n; i++) { result *= i; } return result; } console.log(factorial(69)); console.log(fact...

I am trying to expose a simple struct via FFI. Is this the best way to do it? I am not 100% sure about the get_text function. This is taking the string out of the struct and cloning it before returning a pointer to it. I suspect this is going to leak. Whats the best idiomatic way around this? Do...

This question combines two other codebases that I have put on this site: Questions: Coalescing ranges that have the same label Simple sharding of delimited files to more sophisticated Repos [lrng][repo 1] (handles labeled ranges) [parpar][repo 2] (handles simple sharding and multithreading...

I've written a small script that automates the tasks I previously did manually for deploying onto our kubernetes clusters and I am quite happy with the results I have, but I do think that what my approach was (building a command and executing it at the end) could probably be improved.

Will be very grateful for thoughtful code review. I needed hash table (again) and I wrote one. Code here is here https://tinyurl.com/hashtable-c or inline: #ifndef HASHTABLE_DEFINITION // single file library cannot use pragma once #define HASHTABLE_DEFINITION // https://en.wikipedia.o...

I wrote a blocking serial port library, Blocking serial port C library, but prefer non-blocking so wrote this library where user can specify callbacks. So it is event driven. The code assumes C99 or better. How could this be improved? The example is fairly custom to working in the UK with the...

I am refactoring some legacy code. The code makes heavy use of hard-coded file path strings. I am unsure what to do with these and, more generally, what the best practice is for storing and retrieving file paths. Abstracting away from the details, I have an abstract base class which contains a p...

I have created the following code that takes as input two numbers and a list. The first number N says how many elements are in a list. The second number K says how many numbers are in a list ( if K=3 it means there are 3 different numbers in the list starting from 1 to K (1,2,3) ) . The program s...

I use self-closing bodyless for loop to quickly find an element within an array or collection. Learned it from a Java teacher.
