im a beginner of C and i am trying to code with pointers to void. My goals would be to sort every type of record with one function.The code works and compile but i think that i could write it better. I am searching for advice to improve my skills,thanks for the attention, i leave the code down: m...

I'm porting this code to Java and after a few tests all seems ok but I need to know if I'm doing this right. The code takes some colors and create a color ramp for maps and other stuff. You can see the original Javascript version working here. I removed the "slider" part and fixed the amplitude t...

I have this function at the moment def isConnected(adjacencyListMap: Map[String, Seq[String]]): Boolean = { // Simple BFS to check whether each vertex is connected val visitedMap = mutable .Map[String, Boolean]() ++= adjacencyListMap.keys.map(vertex => vertex -> false).toMap v...

I have something like this in typescript isSendCalculationDisabled(): boolean { return (this.calculationResults.state === CalculationState.SENT) || !this.assignmentService.assignmentEditable || (this.buildingImageRenderService.isRenderReady === false) || (this.calculationResults.reaso...

I want to split a dataset recursively according to one of its attributes (attVal) and based on others datasets attributes values like the following : Given the initial dataset ds1 and the datasets to split with ds2, ds3,..., i want to split by min(df2) and max(df2),min(df3) and max(df3)... the da...

Below is the code for mergesort using multithreading, will this code run for large number of inputs or does any other part of the code needs changing #include<iostream> #include<thread> #include<mutex> #include<vector> #include<functional> #include<fstream> std::mutex mu; void merge(std::vector<int

Project Euler 7: What is the 10 001st prime number? \n I currently have this code: let primesfound = 0; for(i=0;i<Number.MAX_SAFE_INTEGER;i++){ if(isPrime(i)){ primesfound++ } if(primesfound==10001){ console.log(i) break; } else{ console.log(i + `and ${primesfound} found`)...

Take the words dataset from stringr. An R4DS exercise challenges the reader to check if there are any words in that dataset that contain every vowel. My presumably correct solution, using five calls to str_detect, was as follows: library(stringr) words[apply(sapply(c("a", "e", "i", "o", "u"), fun...

I was wondering if it would be possible to optimise my python script? It is designed to quickly generate and print all the prime numbers under some inputted number. It is fairly fast currently, and I am wondering about its current time complexity, however, I'm also curious to know if there are fu...

Background I am doing an exercise in clojure to make a function that can determine if a number is an Armstrong Number or not. The solution I came up with us a bit more complicated than it would be if there was not a requirement to take 17 digit numbers which start to cause calculation errors with...

I made a maze generator in python that outputs in CLI. With mazes that are extremely big, it can take a while to output. I want to know if there is any way to increase the efficiency of this code. Here it is: import random def mgen(size=3, disallowedcoords = [[]]): try: def canmove(co...

Goal This code combines two matrices, diagonalizes that matrix, and finds the right and left eigenvectors, right and left eigenvectors are normalized with respect to each other, then it is multiplied by an exponential function that is a function of the Eigen values and plots the output spectrum w...

The below code filters my contacts according to a search term the user typed. Is there a way I can make it dynamic? contacts = contacts.filter( contact => contact.firstName.toLowerCase().includes(search) || contact.lastName.toLowerCase().includes(search) || contact.title.t...

A function that asks for user input according to some criteria and again on the same line if the criteria is not met. It requires that escape character sequences be enable. """ Ask for user input according to some criteria and again on the same line if the criteria is not met """ __all__ = ['inp...

The standard HTML range input element suffers from a number of limitations that caused me to implement the web component presented here. First, it is unnecessarily complicated to style the standard HTML range input element to make it look the same in all web browsers (see here and here). Second, ...

I'm in the early stages of learning Racket, and decided to have a go at the tower of Hanoi. I did this without any reference whatsoever, so everything is up for review, including the algorithm as well as my code. In order to move n disks from a from peg to a to peg, we need to... move the top n-...

I wrote this module to find the Hamming distance between two strings. (It's a problem from exercism.io's Haskell track.) As I saw it, the problem has two distinct parts: check if the length of the two strings are equal (if not return Nothing), and recursive pattern matching on equal-length string...

Based on this comment about reify, It acts like @property, except that the function is only ever called once; after that, the value is cached as a regular attribute. This gives you lazy attribute creation on objects that are meant to be immutable. I have this custom reify class: class reify(obj...

I decided I wanted to make a console-like system. So, I started planning & creating it in c#. Currently, all that it is is a processor of sorts. It reads all bytes from a file (R:\disk00), and then executes them, somewhat like a CPU. display.pyw is a simple pygame application which reads R:\disk0...
