Choices I made

• I displayed the result in a recyclerview where each cell process what it should display according to it's number. It allow us to be unaffected by the limit chosen by the user.
• I didn't built any architecture or worked on several git branches as it seemed irrelevant on a project with this size, data flow & future perspectives.
• I took the liberty to interpret some cases, for example if I enter buzz, 5 before fizz, 3, should we display buzzfizz or fizzbuzz ? In a work environment I would have asked what was more relevant to the use case or at least acknowledged the choice I made but here I just added a comment where it seemed justified.
• I commented the key functions only but we may be extend the code coverage if needed, if we want to build an sdk for example.
• I tested the data processing part only. It seemed logical as it is the heart of this application logic.
• This readme is in english even if the target audience is likely to be french natives. It seemed logical as 1. this is a readme and 2. the subject was in english too.
• I used Rxkotlin as it is the technology I'm familiar with

If I had more time

• we may add some help with the form filling which is a bit annoying for the user. We could remember what he entered last time and/or suggested some word and period above the keyboard. Example:

• We could build an interface that allows you to add N fizz / buzz words. Every time you fill a cell with a word and a period, another one pops up bellow with empty fields (or you have a "+" button)

• The help of a designer would be a big plus, the UX isn't that great and on the UI part we're a bit too close to the raw and outdated material design
