Our Friday quest for system administrators and not only
We in the company "Flant" love IT-quests - those who got a job with us know this very well. And it was so wonderful that in my free time I was lucky to come up with another puzzle.
The decision to publish it in the hub of system administration is due to the fact that to a greater extent we identify ourselves with this category of IT specialists, however, the full passage of the quest requires ingenuity in the context of more general IT competencies. In general, if you, like us, even (and especially!) On weekends (or maybe even on Friday?) Want to occupy your brain with interesting tasks - welcome! We even promise a prize to the fastest winner.
Go!
To start the quest, just look at the picture below. Enjoy! ')
Notes
Please do not post the final answer in the comments without the spoiler tag.
The winner will be the first user of the habr (excluding the employees of our company, even if they mostly have not seen this quest yet) , who left a comment with the final answer of the quest (we believe that you will understand when this answer is received).
To the winner we will send a DIY kit based on the Arduino - Matryoshka Z.
