GUESTS

We welcome contributions in other languages. So far we have had one guest submitting solutions in Python in the past. Last week, we didn’t receive any contributions from guest.

Task #1

Write a script to print first 10 Sexy Prime Pairs. Sexy primes are prime numbers that differ from each other by 6. For example, the numbers 5 and 11 are both sexy primes, because 11 - 5 = 6. The term “sexy prime” is a pun stemming from the Latin word for six: sex. For more information, please checkout wiki page.

Task #2

Write a script to implement Lempel–Ziv–Welch (LZW) compression algorithm. The script should have method to encode/decode algorithm. The wiki page explains the compression algorithm very nicely.

I must confess, it took me many years to get my head around the compression algorithm, I finally understood while doing research for the task. So thanks to Perl Weekly Challenge, I can proudly say that now I understand the compression algorithm. I hope you will enjoy this task as much as I did.

Task #3

Write a script to use Amazon Pinpoint API. For more information about the API, please visit page. The API task is optional but we would love to see your solution.

Last date to submit the solution 23:59 (UK Time) Sunday 25th August 2019.
