The task is to find the longest common prefix. While I had no trouble to find the solution, I'm interested in the statistics of my code:
Runtime: 7 ms, faster than 56.36% of C++ online submissions for Longest Common Prefix.
Memory Usage: 9.3 MB, less than 54.46% of C++ online submissions for Longest Common Prefix.

Consider the MCG with parameters: a = 23, M = 10^8 + 1, and let the seed be 47594118. (This is the original MCG proposed by Lehmer in 1948.) Apply the Kolmogorov-Smirnov test to the first 1000 random numbers (including the seed) from this generator. Compute the KS-statistic and find its p-value. What is your conclusio... | stackexchange/codereview |
I'm doing a CodingBat exercise and would like to learn to write code in the most efficient way. On this exercise, I was just wondering if there's a shorter way to write this code.
monkeyTrouble(true, true) → true
monkeyTrouble(false, false) → true
monkeyTrouble(true, false) → false

I'm writing a URL validator. Firstly, it checks for special characters in the input. Secondly, it adds 'http://' and checks for validity.
/* Returns true if url is valid */

I have two questions.
Does it make sense to test that an event will not be fired?
If yes, what is the best way to accomplish that using the xUnit framework?
For example I have a class with a single property Mark,
public class Box : INotifyPropertyChanged
{
private Marking mark = Marking.None;

Today I tried to learn how to make a simple garbage collector for a future project, it didn't need to be fast nor complex nor optimal, it just needed to work. After lots of searching and reading, I was able to make something work.
So, how can I improve it from here? At some point I guess I'll have to ditch the std::arr... | stackexchange/codereview |
I wrote this code, based on the Newton-Raphson method, to find the square root of a number. I'm wondering how I can optimise this code, as I am out of ideas.
#include <stdio.h>
int main(void)
{
float n, x, i;
printf("Enter the number you wish to find the square root of.\n");
printf("\n");

im developing a program that will read text files and convert it to JSON format dynamically. Users are able to input the key name and their respective digit to slice the index from a raw text file. Everything is working fine when reading a small size file, but whenever the text files is huge, the program will load like... | stackexchange/codereview |
I have a string like "food | dairy | milk". The string may consist of more or less words. How do I turn it into a dictionary {'food': {'dairy': {'milk': {'eco': {}}}}}?
The only way I could achieve it was to create a string and then turn it into a dictionary using exec. I understand it's messy. How could I improve on i... | stackexchange/codereview |
I'm posting my code for a LeetCode problem. If you'd like to review, please do so. Thank you!
Problem
Two strings X and Y are similar if we can swap two letters (in different positions) of X, so that it equals Y. Also two strings X and
Y are similar if they are equal.
For example, "tars" and "rats" are similar (swap... | stackexchange/codereview |
In working on this answer it occurred to me that it might be interesting to further expand the idea.

Background
I came up with this solution to a question that I posted on stackoverflow. It uses Tkinter to create a file select dialog window and raise it to the topmost position from jupyter notebook.
Questions
1) Is there some kind of built in or canonical way to do this in jupyter notebook that I've missed in my sear... | stackexchange/codereview |
