I am implementing a program to interact with hash table, the data to be hashed is just number. It works but I want to know if there is any error like: memory leak,... in my code and how to improve my code. Any help would be appreciated. #include <stdio.h> #include <stdlib.h> #include <math.h> #in...

Here is my attempt at Advent of Code Day 4 using Haskell. A file contains list of number in first line. And subsequent lines have the bingo Cards 7,4,9,5,11,17,23,2,0,14,21,24,10,16,13,6,15,25,12,22,18,20,8,19,3,26,1 22 13 17 11 0 8 2 23 4 24 21 9 14 16 7 6 10 3 18 5 1 12 20 15 19 3...

sp_name return a Dictionary(Of Integer, DTO) using the passed params. I attach VB.NET code. I have to convert the call using dapper. Can you give me some suggestions? _dbHelper.ExecReader( "sp_name", parameters, Function(reader) ...

I make WPF application and I need start "subprograms" (scan directory & send to the API for now, in future - accept incoming files) in MainViewModel, but my solution wrong and ugly. I want to take out some code to the classes, rename methods/properties, structure all members, but I don't know wha...

I tried to solve Stamp Combination problem on Kattis, which basically gives an integer array and a target number. The problem asks whether we can find a contiguous subarray which starts at either end of the array or a combination of both subarrays (also start at either end and must not overlap) a...

My previous question here is still same but i was working on it now i have a solution for it. if any of you has a better solution, it will benefit everyone. Same question but my own solution is different. Code below will run as intended but may need some improvements. drop table if exists ...

I have the following file that is included in others. I realise I need to put in try/except but for the purposes of this question, the below should suffice Function Already done in the example below. Except for try/except am I missing anything obvious? Class I was looking at https://stackoverflow...

I wrote a program that implements the Round Robin planning algorithm. The total number of processes is read directly from the input standard, and for each process the arrival time and execution time are specified. The time interval of each process (quantum) is read from the standard input. I calc...

I am trying to create a dictionary such that the new dictionary's keys come from an old dictionary X and its values come from a numpy array Y. My current code assigns all the keys in X to just one value in Y. import os, json,codecs from collections import OrderedDict import numpy as np def rea...

I'm using this function in a Model to get a list of default values of all attributes its attributes right from the database. // MyModel.php public function getDefaultValues() { $cols = $this ->getConnection() ->getDoctrineSchemaManager() ->

I am using WP with the Avada theme and the built in Star Rating element as well as ACF Pro. Unfortunately I found out that the Star-Rating element adds a rating scheme to the footer of the website without asking. There is also no way to disable this. This is annoying So I created my own shortcode...

I wrote a program that implements the same function as the mv command. I know this is not the best implementation, so I would like some suggestions for improvement, possible problems. What you should change? code: #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <errno.h> #incl...

I wrote a program that implements the Shortest Job First (SJF) scheduling algorithm. The total number of processes is read directly from the standard input, following that for each process to specify the execution time. The average waiting time is also calculated and the order of execution of the...

I made a script where I generate a graph and then color it with four colors. The colorate graph is then drawn using networkx. The program should not put two colors adjacent to oneanother but when you run the program, you can see it does. I really dont know what the issue is, my best guess is that...

Given an Image I with dimensions as {rows, columns}, for every pixel in the image, the following needs to be computed - calc1 = image[i][j - 1] - image[i][j]; calc2 = image[i-1][j] - image[i][j]; calc3 = image[i][j-1] - 2 * image[i][j] + image[i][j + 1] calc4 = image[i-1][j] - 2 * image[i][j] ...

I have developed a program that implements a Priority Scheduling algorithm (Priority Scheduling). The total number of processes is read directly from the input standard, each process specifying the arrival time and the execution time, respectively its priority. I calculated the average response t...

My original question is here Python: token request, SQL user fetch and API calls and as per the comments, I have since refactored as much as code as I think is sensible so was looking for feedback on that I have the files as below. What I'm looking for is some feedback with regards to security, r...

I wrote a program that implements a minimal shell and reads from standard input commands and executes them. Is my implementation ok? I admit that I helped myself a lot with google. Could I have written a better implementation? Also, I tried to check the program with the dash command, because they...

To collect the values of an api, I use three loopings, I would like to know if it is possible to improve this method that I use. a = 9625897 def graph(a): url = f'https://api.sofascore.com/api/v1/event/{a}/graph' response = requests.get(url, headers=headers, timeout=1).json() if 'gra...

AABB: Axis Aligned Bounding Box ALGORITHM: Compare m number of AABB to n number of AABB to find if there is a collision between m and n sets. PROBLEM: Slow implementation for large number of rectangles (m>1000)(n>100000) POSSIBLE SOLUTION/QUESTION Is there any algorithm such that bounding boxes a...

The code below is my solution to the following problem (problem #5 on LeetCode): Given a string s, return the longest palindromic substring in s. I wonder whether my use of iterators is an overkill. They seem to be convenient for calculating the length of the ranges and for constructing the str...

This is an implementation of a Sieve of Eratosthenes as [Symbol.iterator] in JavaScript. Comments welcome, my JS is a bit rusty. Making a class of this is mainly the reason to have fun with the iterator. I will build a generator of it next. UPDATE: inverting the sieve flags removes the need to i...

The full code (works on x86_64) is available on GitHub: https://github.com/anonymix007/libldacdec/tree/fixedpoint At first I used just original floating-point version, but it turned out to be too slow, because used DSP (32 bit, 120 MHz max, 112kB program and 448kB data RAM) does not have FPU. Rew...
