How can I shorten my code for this? There are 6 variable sets of numbers, someone picks a number between 1-63, if their number is in a set, you add the first number of the list to the magic number variable. If it is not, you don't add anything, and move to the next set. I have used multiple while...

I implemented a console version of a news ticker and I will be glad for a code review. It takes a text from the user and displays it for a given period. How may I get it better? #include <algorithm> #include <iostream> #include <cstdlib> #include <thread> #include <chrono> #include <string> int ...

While on SO someone posted this question and I gave it a quick try. My solution passed all the testcases. Link to the problem: Problem: (A) Mike and palindrome Question: Mike has a string s consisting of only lowercase English letters. He wants to change exactly one character from the string so ...

I was trying to implement my own version of matplotlib's hist function and I came up with this: import numpy as np import matplotlib.pyplot as plt import numba as nb from numba import prange import time N = 10_000_000 normal = np.random.standard_normal(N) @nb.jit(parallel=True) def histogram(a...

I need to write an implementation to a given unit test, that cannot be changed. /** * This is the car factory test. For all the tests to succeed, the implementations and the classes you * think might be required, would have to be written. * * Existing tests cannot be modified unless you notic...

I want to be able to create a hierarchy of classes and efficiently lookup them by common class attribute value. So far I've come up with this solution: class IndexedAttr: def __init__(self): self.cls = None self.name = None def find_cls(self, value): cls_by_value ...

I produced this nested loops solution with label for breaking the iteration over two nested collections. Is there (and I hope there is) some more elegant solution that this? (e.g. streams, avoiding the label etc.?) This algorithm should only check the first unitLine from the first unit and if the...

I've gone through the docs in a fair bit of detail and understand that a setState function can be passed a function if the previous state is needed. Here I am trying to, based on the state of a variable, set the state of another variable. This seems logically correct to me, but just feel weird. L...

Please verify jump searching algorithm that I have written and let me know if any bugs are present. I have tested it from my end, but still would like to get it verified for any missing corner scenarios. class JumpSearch { public static void main(String[] args) { int[] input = new int...

I am trying to implement a Left shift/ Right Shift on arrays. I was able to accomplish this using double loops. Can the efficiency be improved? This is the working code for LeftShift/RightShift which is using 2 nested loops. #include <iostream> #include <stdlib.h> #include <stdio.h> struct Arra...

For reasons, I want to implement a predicated version of std::for_each. I know that, in C++20, this is made somewhat redundant or less useful, as we can use std::ranges:views::filter; and that a more robust implementation than the one I present below might use conditional iterators (like Boost ha...

I had to implement a function for getting the Levenshtein distance of two strings for a problem. It linked to the Wikipedia Article for Levenshtein distance and mentioned I can use the dynamic problem solution. Following is my implementation. def levenshtein_distance(s, t): m, n = len(s) + 1,...
