This challenge was part of the European Cyber Week Qualification.

Challenge description

The goal of this challenge was to find the transcription of a text. To find the transcription, for each step, we can sent two entries and see the result of the output. Once these two tests done we received a sentence and we need to transcript it in letters. This challenge was cool and funny this is the reason of this WU.


After some manual tests the only one option was to script the solution. Indeed, after some manual tests , I see that there will be lots of test just for the first step.
