A number chain is created by continuously adding the square of the digits in a number to form a new number until it has been seen before.
For example,
44 → 32 → 13 → 10 → 1 → 1
85 → 89 → 145 → 42 → 20 → 4 → 16 → 37 → 58 → 89
Therefore any chain that arrives at 1 or 89 will bec...
I made this piece of code as first step for a bigger project to iterate and manage bookmarks: open, rename, place in new folder structure, or delete each one of them. This first step is a parser to get a useful json file with the structure and data of each bookmark and folder. I've usex regex ins...
I built this regular expression pattern using grouping and named groups after Landsat's new product identifier pattern. It looks like this:
(?P<prefix>L)(?P<sensor>[C|O|T|E|M])(?P<satellite>0[14578])(?P<delimiter>_)(?P<processing_correction_level>(L1(?:TP|GT|GS)))(?P=delimiter)(?P<path>[012][0-9...
The title explains the code but I'll give examples.
The number 81 fits the code because 8+1=9 and 9^2=81.
The number 512 fits the code because 5+1+2=8 and 8^3=512.
The number 17576 fits because 1+7+5+7+6=26 and 26^3=17576.
The power of the sum of the digits can be any positive num...
I created a function to calculate the VIX using the old method. However, since I have no sample data, I have no idea whether I implemented my code correctly. Can you please help me check if my code is correct?
Link to its calculation: https://drive.google.com/file/d/1R7Pk8dN5hiXl8pACj-7uKZa5_tY...
Below is an implementation of LinkedHashSet in Java. Although this is limited with its functionality, it will do the basic job.
I used interfaces so then I can use that interface for BST.
//Set interface
package interfaces.set;
public interface Set<E> extends Iterable<E>
{
int size();

I have a 6 x 7 grid for a calendar = 42 DateTimes. I'm trying to display the displayed month/year at the top of the calendar.
If there are 3 months displayed, I only want to show the name for the middle month (October 2018, for instance). If 2 months are displayed, split the name (October - Nov...

But it takes huge time to get the results.
How it works:
It makes request to given url

I wrote a Twitter scraper using the tweepy so I can scrape user information and tweets. Given that the free API doesn't let me get the number of messages per tweet, I had to rely on BeautifulSoup to do so. Here's my code:
class TweetAPI():
def __init__(self, k1,k2,k3,k4):
self.key =...
