Schrödinger's Cat 2

One of my favorite CTF challenges in SKRCTF and I am so happy that I could solve this fun challenge. Before that, I suggest you to do Schrödinger’s Cat 1 first to get an idea of this 2nd challenge and my solution.

How do I find out the answer/flag? It is actually simple but quite a lengthy process. I will try my best to explain it in detail.

At the beginning, I just play around this guessing game by entering 1 or 2 as you can see in the terminal screenshot below.

Of course, initially I thought it is randomized until I restarted the game and tried countless times like a noob. Only to realize it is a fixed question and answer with that specific pattern. And I also realized that since the result is either 1 or 2 (alive or dead) can be interpreted as true or false in boolean and binary. So I come up with this idea: 0 for Wrong (Dead) and 1 for Right (Alive)

From that information, we can find out SKR in binary format which are 01010011 01001011 01010010 01111011 01111101.

Using the information and same idea to find the right answer from the correct answer (from the bot) and you will get something like what I did.

Doing of all that, you just need to convert the binary to ASCII and you will get the flag.

** Flag: SKR{R1gh7_or_Wr0nG} **
