I'm a Haskell beginner and trying to hone my skill by solving algorithmic problems. Here's what I got for maxheapify from Introduction to Algorithms ixParent :: Int -> Int ixParent = floor . flip (/) 2 . fromIntegral ixLeft :: Int -> Int ixLeft = (*) 2 ixRight :: Int -> Int ixRight = (+) 1 . (*...

I don't know what the title should be, but I am having very hard time to refactor my codes. I need some insight and help. Here is the business requirements: An order needs to be created and processed. Order can have different types of items and their process will be different. There will be some ...

I'm making a user interface for an online coffee shop. I need to call methods that have already been created. The user is also able to make customisations to their drink order such as a different choice of milk, brown or white sugar etc. Once the user choice has been made it will add the drink to...

The integration field needs to get recalculated every time the starting or goal coordinates change. I wanted to use the flow field algorithm for a problem that include bigger mazes (= arrays with maze coordinates) with changing starting or ending points every 0.5 seconds. Right now the algorithm ...

Hiii everyone!! This is my third day of learning Javascript through an online class. I learned about arrays and while/for loops today, and to practice all of that stuff the challenge I'm working on is to make a function that produces (n) terms of the Fibonacci sequence in an array. So I'm hoping ...

I have to do a program in php that reads files like that and gets records about glider: https://xcportal.pl/sites/default/files/tracks/2020-06-09/069daro396091568.igc For now i came up with something like that: <?php class Pilot { public $name; public $gliderType;...

I have a code that does a deyster algorithm for an adjacency list. The data is taken from a file. In the file, the first line contains the number of vertices and edges, and the remaining lines contain three elements each (the first 2 are the numbers of the vertices and 3rd are the weight of the e...

In the early days of Basic (1970's when i started coding) the midStr() function used left and right positions directly rather than left and length we now use with mid(). I always found it more efficient in my mind to code using the old midStr() method, so I finally just created some code to do it...

//MEM = initial memory, INDATA, the actual floating point value #define atomicAddFloatX(MEM, INDATA)\ {\ float data = INDATA;\ float prev_mem = uintBitsToFloat(MEM);\ float exchange_mem = prev_mem;\ float input_mem = (data + prev_mem);\ //initially this is what we assume we want ...

I have been trying to improve my Python coding and was just wondering if there was a more pythonic way to perform what I have done so far, namely around the date in the main() function. import datetime import sybase account_list = [] def get_date(): # Date -1 day unless Monday then -3 days ...

I'm fairly new to coding in c and have stumbled upon a problem. The code below is what I have so far. We have two nodes, the first one creates a basic job post with a reference number (an integer) and job name (a string - an array of characters) as parameters, and the second is a list that holds ...

I'm analysing 2 big spreadsheets and I wonder if my analysis is the most efficient. I need to find out which two origins have the most number of same trucks. The spreadsheets look like this: items.csv # item | origin 511 | 123993 14 | 63 152 | 5 998 | 155 213 | 563 66 | 563 ...

Enumerating all fixed-length paths from a vertex in a graph Graph-related classes Base implementations of the relevant classes in my graph library. I'm using C#9 in a .NET 5 project. I opted to use structs for my Vertex and Edge types to disallow null, which simplifies the equality and comparison...

I'm writing a code where a class member, if != -1, set its own position at array. If the value is == -1, the next free index (whose range is 0 too array's length) is used. In this review, I'm more interested in the algorithm, making it faster, accurate and readable than anything else. despite I'm...

So in my free time, I made a discord bot to play around with and learn a bit of python. I'm mainly a java developer. The bot has a few commands that allow it to find and output recipe for cocktails and a few other things revolving around cocktails. In the background, there are 2 JSON files. My bo...

I need to store sensitive strings in DB, so decided to encrypt it in a DB and decrypt it at the application layer. And noticed that it is not so easy to find ready to use an example. Please check my code below. It is based on this damienbod's topic, but I included IV to the string itself and als...
