Description

Homework 1
Instructions
The first homework has to be done by each person individually.
Handing in:
You have to create a public Github repository, that you are going to share with us filling this Google Form (compulsory, otherwise we will not be able to correct your homework). The content of the repository is up to you. The mandatory files are:
• README.md: a Markdown file that explains the content of your repository. This is an example. It is important that for each file/folder you say what it contains. Here a cheatsheet to use Markdown.
• scripts.py: a .py file that contains any solution of the exercise you completed. Alternatively, you can also produce a Jupyter Notebook, where each cell contains an exercise.
• stamps/: a folder that contains all the screenshot that assess the successful exercises you did. You can find all of your submissions in your Hackerrank profile.
For information about collaboration, and about being late check the web page.
Problem 1. The goal of the first assignment focuses on building up your skills on Python. The assignment is done electronically using the HACKERRANK online service available from the following URL:
