About

We use numbers every day. But do you know how many different properties they have? Let's take a look at some of the amazing properties of numbers. After completing this project, you will write a program that knows how to determine whether a number is Palindromic or Gapful, or how to distinguish Spy numbers from others. Numbers can be fascinating!

Generally challenging project. Tasks had multiple targets - update the input and also the output. Some places the text was confusing, like happy and sad numbers.

I learned Hyperskils should provide a more comprehensive look at a project before we start. It would help us design the projects more efficiently.
