# Longest Collatz sequence you can find

## Introduction

The project name is: *collatz*.

You'll give back your project using this protocol:
https://mdk.fr/pages/obiree2uaza2sh-rendu.html

The mail body should also contain the longest collatz sequence you
found.

## Project

Make a program taking *no paramter*, named *collatz.py*, computing
Collatz sequences, and printing its best findings as it goes, maybe
like:

    $ python3 collatz.py
    Collatz from 1 of len 1
    Collatz from 2 of len 2
    Collatz from 3 of len 8
    Collatz from 6 of len 9
    Collatz from 7 of len 17
    Collatz from 9 of len 20
    Collatz from 18 of len 21
    Collatz from 25 of len 24
    Collatz from 27 of len 112
    Collatz from 54 of len 113
    Collatz from 73 of len 116
    Collatz from 97 of len 119
    Collatz from 129 of len 122
    Collatz from 171 of len 125
    Collatz from 231 of len 128
    Collatz from 313 of len 131
    Collatz from 327 of len 144
    Collatz from 649 of len 145
    Collatz from 703 of len 171
    Collatz from 871 of len 179
    Collatz from 1161 of len 182
    Collatz from 2223 of len 183
    Collatz from 2463 of len 209
    Collatz from 2919 of len 217
    Collatz from 3711 of len 238
    Collatz from 6171 of len 262
    Collatz from 10971 of len 268
    Collatz from 13255 of len 276
    Collatz from 17647 of len 279
    Collatz from 23529 of len 282


Your program should never end.
