I wanted to see if there is a better way to write this logic Its calling an API so I can't change the endpoint. I would be happy for any kind of feedback since this is quite critical a part of my application. List<string> lisOfAnswers= new List<string>(); ; if (!String.IsNullOrWhiteSpace(answer...

Please evaluate for correctness, concision and speed. Thanks! private def shiftN[A](list: List[A], n: Int): List[List[A]] = { if (n <= 0) Nil else { val shifted: List[A] = shift(list) shifted :: shiftN(shifted, n - 1) } } private def shift[A](arr: List[A]): List[A] ...

Below is my solution for the CTFP chapter 4 challenges which essentially involves composing partial functions(that don't have defined outputs for all possible inputs i.e. returning a Maybe). The challenge is to implement composition, identity(to satisfy category requirements) and try it out with ...

Here is a simple react app that will list some dummy data and can be filtered by categories (in this case, by user ID) by toggling the button on/off. FilterBtn.js import React, { useContext, useState } from "react"; import DataContext from "../../context/dataContext"; import "./FilterBtn.css"; c...

Idea: create utility function to convert csv files passed thru pandas.read_csv() to Y and X. The function should take the csv table and extract off Y, leaving the table as X. The user passes and identifier for Y as a key or an index (negative or positive). Any improvement is fine as an answer. Co...

JavaScript now has a "optional-chaining" operator ?., which, when applied like this: (null)?.fooMember would yield null. I want something similar in C (albeit more verbose), like this: #define IF_MEMBER(ptr,member) (ptr ? ptr->member : NULL) What could be a good replacement for the 9-character ...

I'm trying to solve the problem given here. I'm getting the required output but the written code looks like code bloat(I mean could've have written better simpler and easy code). Can somebody suggest a better way of doing it. This is my code #include <iostream> #include <string> #include <algorithm>

I have been trying to improve my knowledge with Python and I think the code is pretty forward. However I do dislike abit the coding style I have done where I use too much try except in a content there it might not needed to be at first place. My goal is basically to have a ready payload before sc...

I made an brute force algorithm to find the longest palindrome within the string. This palindrome is a substring of the input. Below is the code. def generate_substrings(string): """ avg time: O(len(string) * len(string)) avg space: O(1) amortized time: O(len(string) * len(...

Problem Statement There is a grid with H horizontal rows and W vertical columns. Let (i,j) denote the square at the i-th row from the top and the j-th column from the left.For each i and j (1≤i≤H, 1≤j≤W), Square (i,j) is described by a character ai,j. If ai,j is ., Square (i,j) is an empty square...

So, I have been doing testing to find the most efficient way to display numpy array images to a HTML, CSS, JS UI (specifically, with CEF Python). I mainly used the method explained here to do the numpy array -> html canvas code. In case anyone is wondering, this test code is based on the boilerpl...

i wrote simple hangman game and am open to any improvement ideas. There should be some simpler ways to make it work. secWord = input("What is the word for others to guess?: ") life = 10 #starting information i = 1 while i < 10: print(".") i += 0.01 #dots so players can not see the word ...

Please can you check if the code i have written follows 4 rules of encapsulation well enough, if there is anything that could be improved or is just wrong iam happy to change (very new to c# sorry if its awful). The code implements the "Dhond't Method" which is a polling system. https://www.bbc.c...
