here is my code for the famous "finding the closest pair of points" problem from CLRS book section 33.4 using a divide-and-conquer approach (this code returns the minimum distance between pair of points). this code works correctly but the run time is too long. As seen in the code, i pre-sort so ...

Would love to have my (simple) Rust SocketServer constructively reviewed. Basically followed the mio docs (somewhat), and threw together a few other things I found around. The goal of this review is to make sure that there aren't any stupid/huge mistakes, and to make sure the fundamentals of bu...

Much to my chagrin, neither STL nor Boost has a cartesian product. Namely, given as arguments one or more iterables, create an iterator producing std::tuples of every combination of elements (with one drawn from each iterator in the order of the arguments). My goal here was to make cartesian_pro...

I am attempting to write up a program in python that will find the shortest path between two nodes in 3D space. The actual domain is the EVE-Online Universe, which is composed of systems connected by stargates. The input to my program is a list of systems, represented as python dicts (JSON). I a...

Ok, this is a simple, unordered, link list. please tell me how bad my code sucks and any suggestions would be greatly appreciated, feel free to be brutally honest if necessary. My only concern is that since C doesn't have garbage collection, I am not sure how to implement such feature in to my c...

Here I upload a very basic Barabasi-Albert network generator and then a percolator which conducts percolation over the network following some rule. I have used openmp to parallelize the loops. Here 3 arrays, maxclus,delmx and entropycalc are shared between the parallel threads and netmap1,netmap2...

While,I am trying to pass "num" and "num1" as reference in the function "rev" ,it is showing error as i am adding the value returned by two rev function. #include<iostream> using namespace std; int rev(int num){ int n = 0; while(num){ int d = num % 10; n = n * 1...

I've recently solved Project Euler's 15th problem stating: Starting in the top left corner of a 2×2 grid, and only being able to move to the right and down, there are exactly 6 routes to the bottom right corner. How many such routes are there through a 20×20 grid? This is my dynamic ap...

I'm coding for a multi-step process. Say there are 3 of these steps. Each accepts the same type of input. Lets begin. This is the object which is passed as input to each step. This object acts as a wrapper for another tye of object, alongside some steps' shared values. Be aware names are invente...

First time around Code Review so please be gentle (and I am happy for comments on which angles of this post are a good fit and which less so). I'm not pretty much used to software engineering in python, and so I figured this might be a match: import pickle class Lexicon: 'a lexicon holding ...

This is a practice project from the book Automate the Boring Stuff with Python. I understand that there are a few threads already with the same problem but I wanted someone to review my code. Thank you for your time. Say you have a list value like this: spam = ['apples', 'bananas', 'tofu', 'cat...

I am working on the following assignment and I am a bit lost: Build a regression model that will predict the rating score of each product based on attributes which correspond to some very common words used in the reviews (selection of how many words is left to you as a decision). So, fo...

I wrote this function that given an array calculates the closest number to zero. The conditions are the following: if the array is empty, return 0 if the array has two values share the "closeness" to zero, return the positive (for example if -1 and 1) Here is my code and link to it: https://r...

I am developing scikit-learn like implementation for C++ it is in the initial stage while developing I've started doubt myself that is this the correct implementation, since here accuracy is more important than robustness. I am still learning C++ and I would like an expert consultation since the ...

Below is my domain model. public class Customer { [Key] [Required] public int Id { get; set; } [Required] public string Email { get; set; } [Required] public string Name { get; set; } } This is how DTO looks like public class CustomerDTO { public int Id { ...

In Sonarcube I am getting an error to convert the following code to Lambda but facing difficulty. private MeterFilter getDefualtConfig() { return new MeterFilter() { @Override public DistributionStatisticConfig configure(Meter.Id id, DistributionStatisticConfig co...

Basically I am building a facade for Mongoose to simplify and promote uniformity. I notice and that Mongoose supports callbacks and promises. I am considering doing the same. I have now 3 functions. A switcher '_doFindOneMongoID(...)' (to call the promise function or to call the callback funct...

This code (pastebin: here) is my first implementation of this style of application in the console. In essence a stopwatch with some added functionality. I was interested in getting some feedback before I refactor and begin adding more features. I'm fairly new to programming and I specifically hav...

I am trying to implement a stack with java. The code for the implementation looks like: public class Stack<E> { Node top = null; public void push(E data) { Node node = new Node(data); if (null != top) { node.next = top; } top = node; } ...

[Sprint Boot] Is it a bad practice to have a method with a RequestMapping annotation returning a String containing a JSON, instead of returning an Object or a JSONObject? I have an external model with custom JSON serializer already implemented. @GetMapping(value = Array("/api/user/{id}"), prod...

I want to read in a data file into a 2D vector. It is known that the data file has three columns but the row number can vary per particular data file. However, the data file always conclude with a sentinel line of -1 -1 -1 and all normal input values are positive. My current code is shown below. ...

I'm learning Rust by learning the Rust programming language book. I'm now implementing the solution for the third challenge. Using a hash map and vectors, create a text interface to allow a user to add employee names to a department in a company. For example, "Add Sally to Engineering" or "Ad...

This is simplified version of my skip-list. The only simplification is instead of K and V I use special class, that resemble big std:pair<char *,Blob>. At the moment the skip-list acts more like a set of int. At the end of skiplist.cc I also added main() function with some test usage. Real co...
