Hi I am working on application which will manage expenses in group of users. I would like to know, how to most effectively get final settlement instructions for users. I have came up with this: @Override public Map<Pair<User, User>, BigDecimal> getSettlementInstructions(Group group) { ...

getFinalImageData(:UIImage) takes a UIImage and downscales its size dimensions (to 400 points, in this example) and returns it as Data that has been compressed to be within the byte limit (using the two UIImage extensions). This function works great but I would love to get some other eyes on it. ...

We are into a scenario to refine code review standards for a team of 50 contributers on a single GitHub repo(using GoLang). It is not difficult to convince obvious bugs & performance hits in the code. For any given code change from a contributor, there can be multiple views on refining the code c...

I started playing Pathfinder: Kingmaker, and very soon ended up in a room with 6 levers, and a task to open a secret door by manipulating the levers. I assumed that the correct position for all the levers is up. But when you flip a single lever, one or two other levers also flip. For example, if ...

Please do check my code and correct my mistakes. what I want to do is combine numbers then filter out those combinations if they exceed some criteria, for example; if the combination contains more than 4 even numbers, then it should be eliminated from the list. I have read that range function can...

I am a beginner in C language. I studied all night and did my assignment. But I wonder if there is a more efficient way. The original structure is this. typedef struct student { int id; int prob_1; int prob_2; int prob_3; int total_score; char grade; }Student I used typed...

Made a simple snake game using C and raylib for graphics, Would like to be critiqued on the clearity and efficiency of the code. #include <raylib.h> #include <stdlib.h> #include <stdio.h> #include <string.h> #include <stdbool.h> #define DIRECTION_UP (Vec2i){0, -1} #define DIRECTION_DOWN (Vec2i)...

based on this stackoverflow topic: https://stackoverflow.com/a/12150289/15270760 I have decided to create a simple NTP client displaying difference between NTP server response and DateTime.Now called right after receiving NTP response. I was just curious of the result. I have read both RFC's 2030...

I'm fairly new to coding and am trying to learn more about best practices. I wanted to have an nestedArray of objectArrays, and I wanted to be able to sort the elements in each objectArray based on matching certain property values with some in the preceding objectArray. This is what I came up wit...

I've a player module export default class Player { upPressed = false; downPressed = false; constructor() { this.playerWidht = 15; this.playerHeight = 175; this.x = 10; this.y = (750 / 2) - (this.playerHeight / 2); // 287.5 this.xVelocity = 0; this.yVelocity = 0; ...

For apps which don't have significant layout changes between the iPhone and iPad versions, I usually set the constraints of all UI elements (views, labels etc.) as fractions of the current device screen's width and height, in order to scale the content for different sizes and aspect ratios. The w...

Exponential Search is an optimization over binary search. Conceptually, when searching for a number target in a list of numbers nums, exponential search first finds into which power-of-two sized bucket nums[2**p: 2**(p+1)] the target falls into. E.g., if nums has a size of 30, then the buckets ar...

This is my accepted submission for LeetCode. The problem is "You are given a 0-indexed integer array nums. An index i is part of a hill in nums if the closest non-equal neighbors of i are smaller than nums[i]. Similarly, an index i is part of a valley in nums if the closest non-equal neighbors of...
