What is the best way to refactor the following method? def notification_redirection_path(notification) notifiable_type = notification.notifiable_type notifiable_id = notification.notifiable_id action = notification.action if action == "commented" route = case notifiable_type ...

Given an array of ints, return True if the array contains a 2 next to a 2 somewhere. has22([1, 2, 2]) - True has22([1, 2, 1, 2]) -False has22([2, 1, 2]) - False I do aware of a quick solution by iterating the list in a for loop and comparing current and next items for equality until ...

I tried solving this problem on SPOJ, in which you reverse the digits of two numbers, add them, and print the reversed digits of the sum. (When reversing, leading zeroes in the result should be dropped, and trailing zeroes in the result shouldn't happen.) I submitted this code and it did not get...

The list is pretty simple, here is my code: ILinkedList.java package datastructures; public interface ILinkedList<T> { public enum posForOperation { BEGGINIG,BEFORE ,AFTER ,END } public class Node<T>{ T data; Node next; public Node(T data){ this.data...

I've very recently started using OOP paradigms for the code in my work (academic research). As an exercise I tried coding this quick scoreboard. I'm not interested in improving the 'display' part, I know there would be a lot to do there, but does my use of classes make any sense? import os from...

jQuery is completely new to me and I just wrote the below code to show the slide in the querystring and hide the other slides in the flexslider. However, a few things: I know this code probably isn't the best way to write what needs to be accomplished. There has to be a better way because obvio...

Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”. Is this the best way of doing this? def fizz_buzz(num): i...

I want to create a list of random integers in the range [0, 9], that sums up to 100 in Excel, using VBA. The list should be printed in a single column. The routine I've written is as follows: Sub RandomList() Dim arr(100) As Integer Dim i As Integer i = 0 Do arr(i) = In...

I am trying to detect whether a condition is being returned true or false. Only problem is I have a bunch of if/else statements. Is it possible to refactor this in less lines? Maybe a for loop or re-writing my markup? $(document).on('click', '.cert-modal-btn', function(event) { event.preventDefa...

I am using the following code to retrieve the URL of a random image in a remote folder that I own. As a newbie and although this is working I would like to know if this is done properly, if it could be improved and if there is any security issue with this approach. I am using json_encode and js...

So I have this piece of Python code that essentially takes a tuple, then modifies the second (and every other) element by prepending a string to it. Unfortunately the only way I can think to do it is convert it to a list, step through, edit and then convert back to a tuple. It works so I can't ...

I have a query which returns direct status changes (no intermediary changes) of user statuses. SELECT u.id uId, pro.id pId, uaud2.status oldStatus, uaud1.status newStatus, uaud1.statuschangereason, uaud1.statuschangedate FROM cs_program p...

I am using the following code to password protect pages on my site. This is how I am including it on a page: <?php include("/path/to/password_protect.php"); ?> After that line I have the rest of the page code, which is not displayed if the user is not logged in. This is the password protect c...

Introduction Suppose you are given three elements \$a, b, c\$ with respective weights \$1, 1, 3\$. Now, a probability distribution data structures will return upon request \$a\$ with probability 20%, \$b\$ with probability 20%, and \$c\$ with probability 60%. The API for my probability distribu...

My intention is to have a class A and class B. class B has a std::list from a pointers of class A. I need three operations to complete very fast: Inserting new A elements into the list in B Removing these very fast Iterate through the A-s already registered in B sequentially. Their order is irr...

Public Class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim rotation As Vector = New Vector(45, 0, -90) Dim delta As Vector = New Vector(10, 10, 10) Dim result As Vector = InverseVector(delta, rotation) ...

I thought this would be a fun exercise to use SQL to participate in the June 2016 Community Challenge, so I did. Yes, you may call me crazy! I had to write a few little things to help me, I needed a function to simulate a dice roll, but functions do not support the using of RAND() function becau...

I have a class which deals with managing medical data. I have to calculate some algorithm value but there are lots of conditions. Now I want to place these codes in a very readable and maintainable way. May be if some design pattern can help but not sure. Can someone suggest me what is the best ...

I need a generic data structure that ensures that its elements are unique. C# has HashSet<T>, great! As it turns out, the elements have to stay in the order in which they were added, too. This sounds more like List<T>. I tried to create my own: using System.Collections; using System.Collection...

Im Trying To Show A PNG Image With Two TextBox On It Instead Of Form(This Is What I Want) I Know That C#(Winform) It's Not Good At Transparent But I'm Really Looking Forward To It!!! I Have A Project That Opens This Png Image Itself But I Want This Image To Be As My Form(With Textboxes)! Any Idea?

What I'm trying to accomplish is to get the code to format the number according to these rules: If number is integer smaller than 10^9 or bigger than 10^-6, write it as integer, else write it in scientific format, rounded to 8 decimal places at most. If number is decimal smaller than 10^9 or bi...

I'm having trouble optimising the project euler #50 exercise, it runs for around 30-35 seconds, which is terrible performance. The prime 41, can be written as the sum of six consecutive primes: 41 = 2 + 3 + 5 + 7 + 11 + 13 This is the longest sum of consecutive primes that adds to a pr...

I am trying to create some kind of FIFO stack from sql tabel i.e. If limit of table is 50 records and if it's full, after insert, Last record in table will be deleted and new will be inserted. here some code create trigger LimTab after insert on Posts declare tableCount int; Set tableCount=(s...

I wrote a few simple extension methods that allow to traverse a hierachically data structure depth-first or breath-first using LINQ: Usage: public class Item { public Item(string name, params Item[] children) { Name = name; Items = (children ?? new Item[0]).ToList(); ...

I am learning Clojure by implementing a simplistic resource reservation system. At its core are the two functions for placing/canceling reservations for a given resource: ; thread-safe map of {resource -> #{reservations}} (def known-reservations (atom {})) (defn place-reservation [new-res] ...
