Check out current team members.

GUESTS

Last week, one of the team members, Roger Bell West, submitted solution in Postscript. He initially started with Perl5 solutions only. Few weeks ago, he started submitting Perl6 solutions as well. Now he went beyond my expectations and did it in Postscript. This is the proudest moment for me, when I see how members going out of their comfort zone and trying new challenges every week. I hope it inspires other as well to try something different and share with the team, so we also learn from their hard work.

Task #1

Create a smallest script in terms of size that on execution doesn’t throw any error. The script doesn’t have to do anything special. You could even come up with smallest one-liner.

Task #2

Create a script to implement full text search functionality using Inverted Index. According to wikipedia:

In computer science, an inverted index (also referred to as a postings file or inverted file) is a database index storing a mapping from content, such as words or numbers, to its locations in a table, or in a document or a set of documents (named in contrast to a forward index, which maps from documents to content). The purpose of an inverted index is to allow fast full-text searches, at a cost of increased processing when a document is added to the database.

Here is a nice example of Inverted Index.

Task #3

Write a script to use PayRun.io API. Please follow the page for more information. The API task is optional but we would love to see your solution.

Last date to submit the solution 23:59 (UK Time) Sunday 8th September 2019.
