I created the following function, permutations, to produce all permutations of a List[A]. Example: scala> net.Permutations.permutations("ab".split("").toList) res3: List[List[String]] = List(List(a, b), List(b, a)) Code: object Permutations { def permutations[A](str: List[A]): List[List[A]] =...

I am working on a part of an IoT project where I have been given a task to develop a mechanism to store data locally when there is no network coverage or if the network is down for some reason. Our application is architected such that, every hour we store the feed/sensor data to a bucket i.e.loca...

I've created program like in the title. Actually I know I could use regex to create pattern and then do some actions from it, but I think my code is clear enough (at least for me :P). There is little thing to correct which is InputMismatch exception that isn't handled. What do you think about my ...

I'm a beginner programmer and i'm looking for interesting projects to improve my low skills. I tried one day to improve my skills by trying to create a small game in which a user owns a cat, and has to feed it and clean it. My main aim of the game(which yet has many illogical things like the neve...

I am trying to implement merge sort in a linked list in c++. When I execute my code, it runs infinitely no. of time. When I debug it, I found that my mergesort function runs only for the left half infinite number no. of times. That function never called for the right half. I am pasting my whole c...

I'm working with a local Git repository in some .NET code using the open source library used by the Visual Studio Tools for Git, LibGit2Sharp. I need to create some submodules. The code I used was: $ git submodule add <remote_url> <destination_folder> $ git submodule init $ git submodule update ...

During the implementation of strategy-pattern, I thought about speaking code (unfortunately I don't know the actual terminology for that) and came up with this implementation: class Data { clone() : Data { return Object.assign([], this); } } interface Operation { on(data : Da...

I'm trying to implement the following code in Java EE (Java 11) to access a datasource in Wildfly 20. The objective is to close implicitly the JNDI context and the SQL connection: try (InitialContext context = new InitialContext(); Connection conn = ((DataSource) context.lookup(pool)).getCo...

I have a 2D array of fixed size and I've implemented a FIFO function. So, the array will always be full before it reaches the FIFO function, then the FIFO will remove the oldest array, move all of the arrays up by one and then add the newest array to the other end. Basically a queue. Now, this co...

Six month ago I started studying C as my first programming language and a couple of weeks ago I decided to write snake as my first program. The program is written with ncurses and contains four modules: main, layout, controls and gameplay. I haven't added any features yet (score, pause, welcome s...

Previous question with background here I would like advice on improving a FIFO algorithm for a 2D array that I've developed in ANSI C. I have written code that uses this algorithm for test purposes. Random numbers are put into an array until all elements are full. The program then asks the user w...

Can anyone tell me how I can start to optimise this query or recommend anything SELECT t1.id ,( SELECT CASE WHEN COUNT(s1.id) > 0 THEN 'Y' ELSE 'N' END GIANT FROM ccp.comms_matrices s1 WHERE (s1.id = NVL(t1.comms_matrix_id, 0)) AND (s1.iod_id IS...

Can this class be improved? Is this good OOP design? How can I make this faster? my goal is to improve this script; Although it is not the main objective, I am also open to hearing opinions based on documented and exemplified improvements. Class/library Description: [BOH] Basic Output Handler...

I'm working on an app to compare SDKS (their churn and acquisiton rates). I have created an API with two separate endpoints. The first, compares one sdk to ther other and spits out that data for each sdk. The second, simply gets general information about a single sdk. I'm merging these objects in...

I would like to know if my registration system is secure. I'm not sure if it is secure, as I'm new in development, and I'm afraid that the system is flawed Also, I'm not experienced in object oriented programming, I would like to know if my script looks a bit like OOP or is simply a set of proced...
