A little over a week ago I posted my basic brainfuck interpreter here. I have since improved the interpreter on all suggested points except two minor details. (position of parsing error, which should be obvious from just the error in brainfuck; and a problem that would only occur in a program wit...

I'm writing a console application for managing and tracking characters, monsters, turn order and conditions applied to make my battle run faster in DnD. The following code works perfectly on windows but when I tried to compile it on my laptop, which runs linux, it no longer works. I input a name...

I am working on a project on VBA where the objective is to have a "program" that fetches rates from a website called X-Rates, and outputs to excel the monthly averages of a chosen country. Initially I was doing simple XMLHTTP requests and output to Excel the results. But now I have tried to d...

I have to create a new table from the existing one which is something like this Name | Return Ab | Y Cd | N Ab | Y Cd | Y Cd | N Cd | N I want to count the frequency of the Return (y/N) grouped by the name. So far i could is Select Name,coun...

This snippet is about two (brute-force) algorithms for solving the traveling salesman problem. Since there is plenty of boiler-plate code, I arranged a GitHub repository for the entire program, in case someone would like to run it. But these are the classes I would like to get reviewed: (Asymme...

I have this code (which works well), to login in some experiment login form that I did to test: import requests import re def get_page_data(regex, page): match = re.compile(regex).search(page.text) if match != None: return match.group(1) return 'no match found on {}'.format(...

I've created my first Laravel package. It provide car data like Makes, Models, Years and Options (the different vehicle configurations for a particular model/year). This is the github repository of the package: https://github.com/gerardojbaez/vehicle I will appreciate your comments and opinions...

I'm implementing the Two-sample Kolmogorov-Smirnov test in MATLAB. I must admit I know very little of formal statistics and was simply trying to implement the description in wikipedia's page. Right now I take as input the two vectors to be compared x1 and x2, and optionally the p-value that the ...

I've solved this question. Wasn't sure if I was suppose to use a dictionary in this case, as the question was to use a dynamic array, but I didnt know how else to do it. Was wondering if I can get feedback on my code or if there's a better way to approach it: import Foundation // reads input ...

My solution correctly solves the problem, but I would like to optimize its performance. For a capacity of 7 and bars = [ 4, 1, 1, 2, 1], the output is 7. def knapsack(capacity, bars) if capacity == 0 || bars.nil? || bars[0].nil? return 0 end solutions = [] sum = 0 (...

This question is a follow up from my previous question. I am working with some wireless communication in Arduino. 979797 is the address of the transmitter. I have written the following code to check the address first before processing the data. My main concern is speed of computation. void p...

I recently started learning about algorithms and data structure's. I decided that for every algorithm I learn about I'll implement it without looking at any pseudo code or actual code. I have implemented Quick Sort using Hoare's Partition. The pivot is the last element in the array. Can someone ...

I need to write a function in C which performs a checksum using the rule "add without carry". As I understand it, the "add without carry" concept is equivalent to the bitxor operator and given that the bitxor operation is associative and commutative, I am relying on that to perform the calculatio...
