I'm taking an online course in website development and we're going over JavaScript ES6, but my professors lecture and notes I've taken we're not very helpful more resourceful with the assignment I was given. Using proper ES6 methods, I was asked to create a class for Vehicles and two Subclasses f...

Stumbled upon this interview question: Given a morse encoded sentence with no spaces or separation between letters or words and a list of words contained in the message, decode it. This was my solution (and a test case with the jack and jill sentence): static String[] alpha = {"a","b","c...

The problem is to find the unit's digit of the b to the exponent of e. This code has worked for every taste case I've thrown at it, but it doesn't seem to work when I submit it. I can't find anything that would cause an error. int main() { int n, b, e, c; cin>>n; while(n--){ cin

This is my first game and I'm really proud of it, but I think is horribly messy. Any way to improve it? #HANGMAN # Valid Word Checker def valid_word(word): ill_chars = ["!","@","#","$","%","^","&","*","(",")",",",".", " ","1","2","3","4","5","6","7","8","9","0"] for i in word: ...

I am trying to set timeout for tasks which executed by scheduler in Java. I managed to write necessary codes, they are working well but I guess something is not right. I have scheduler's thread pool so each thread can work with different tasks. Inside of the work, I get another thread from thre...

I have a Tree structure represented by a List, which I want to get it flattened. I wrote the function below: List<Entry> flatTree(List<Entry> toFlat, List<Entry> destination) { for (Entry entry : toFlat) { if (CollectionUtils.isNotEmpty(entry.getEntries())) { this.flatEn...

I am looking to get all unique combinations from two strings, for example: STRING 1: "OK" STRING 2: "OK" Desire output OKOK KOOK OKKO KOKO I couldn't find any useful information that can help me to get all unique combinations from two strings, only for one. Two mentions: I would like to ge...

I wanted to implement a thread pool to test my knowledge of various modern C++ features. The end result could be better, but I need a review as I'm not sure about delicate things especially regarding synchronization and variable argument passing and of course recommendations on improvements of th...

I've been following this question pretty closely, reading comments and everything because the "reasoning part" seemed... blog-ish. By reading this answer and the comments under it + the way the reasoning is worded, if seems like the author wrote this question only to write the reasoning part, th...

I could barely get this to work... It seems there is redundancy as the dates are repeated twice, for example. Is there a way to simplify it? WITH total AS ( SELECT COUNT(type) AS total FROM loan_loan WHERE loan_loan.created_at > '2019-08-15' and loan_loan.created_at < '2...

I'm trying to resolve this kata from CodeWars. Kata exercise You are at position [0, 0] in maze NxN and you can only move in one of the four cardinal directions (i.e. North, East, South, West). Return true if you can reach position [N-1, N-1] or false otherwise. Empty positions are mark...

I'm new to C#, I programmed a little in java in the past.I had the two previous exercises reviewed here (permCheck, cyclicRotation, with a 100% score, just like this one), and I'm applying what the accepted answers contributed to me.Even though the site expects names like public int solution(int ...

Given a start and end of a range as string, for example: String start = "1230000"; String end = "1285999"; Generate the shortest list possible with prefixes that include the whole range, so that for any number from the given range there is a list elemnet which can be used as a prefix. For ab...

You are given the marks of N students in 3 subjects namely Data structures, Operating systems and DBMS. You have to rank these students. The criteria to rank the students is as follows. 1.Students with higher marks in Data structures will be ranked higher 2.If two students score same marks in Da...

Probably a dumb question.... I'm trying to use Gauss-Siedel iteration in Matlab to show that the solution to a system of equations diverges, but when I run the program the solution columns aren't lined up right. I've tried different, uniform spacing ... doesn't seem to help. I think it's some...

I have an implementation of the sqrt function that uses a combination of IEEE 754, packed bitfields, and the Newton-Raphson algorithm: union decompose { double f; struct decompose_s { mantissa m:52; exponent e:11; sign s:1; } __attribute__((packed)) o; }; dou...

How can you change the margins in the memory puzzle game code to make them smaller so the game board is larger and easier to see? ( lines 18 &19) assert (BOARDWIDTH * BOARDHEIGHT) % 2 == 0, 'Board needs to have an even number of boxes for pairs of matches.' XMARGIN = int((WINDOWWIDTH - (BOARDWI...

I am creating a program where you guess the coordinate and if you get it right you win but if you get it wrong your attempts go up and your max attempts go down but I don't know how to do that. here is my code # Locator Game Must find both coordinates to win. # Difficulty = very hard # Advanced ...

I need better logic that would allow this search to perform quicker and more efficiently. In XAML, I have a DataGrid and a TextBox. Both need to be present. I'd prefer that as the user types in the TextBox, the Grid is filtered by one or more columns. Not that the user needs to click a "Submit...

Hi :) Im obsessing a bit about something that seems important, the readability and the "understandability" of code so it can be shared (communication). I just remembered Reinderiens previous answer "its a finer art of programming". I guess im just looking for feedback. Is this program going in...

https://leetcode.com/problems/queue-reconstruction-by-height/ Suppose you have a random list of people standing in a queue. Each person is described by a pair of integers \$(h, k)\$, where \$h\$ is the height of the person and \$k\$ is the number of people in front of this person who ha...

This is the final version of both maze generator and solver that I posted last weeks from my other account (which I no longer have). For those who did not check it there are 2 modules included here: 1. Maze generator: Generates mazes using 9 different algorithms (Binary Tree- Sidewinder - Aldou...

I was working on a Python little challenge that was a bit more difficult than expected: format any non-negative number so 1000 turns into "1,000" , 10000000 into "10,000,000" and so forth. I managed to do it, but I find my solution not very readable: def formatting(n): m = str(n) # Turn it ...

Here I have a program I made to be an all-in-one D&D dice roller for all the common dice sizes as well as a disadvantage and advantage menu for the d20 and custom size support and even a stat roller (4d6 drop the lowest). It comes in two parts, the main program for the user to run and a subprogr...

Motivation: Partially for fun / learning, but also so I can roll out a custom JSON-like file format for a fighting game I am writing. There are two caveats: you cannot have repeated keys (requires std::unordered_multimap) and the keys are not in order (requires insertion order std::vector on the ...

Selection Sort The selection sort algorithm sorts a list (array) by finding the minimum element from the right (unsorted part) of the list and putting it at the left (sorted part) of the list. Bubble Sort The Bubble Sort algorithm functions by repeatedly swapping the adjacent elements, if the...
