A bunch of buddies challenged Mark, the brightest amongst them, to an escape room problem (two rooms). They know Mark have a variety of data. But for this one they thought even the brilliant Mark would have a tough time determining the reply.

The directions had been following:

“You have half-hour to unravel half one of many puzzle within the first room – if you cannot, too dangerous. If you handle to unravel it nonetheless then ring the bell and we’ll unlock the door to the proper of you. Enter the door, sit down on the desk and clear up half two of the puzzle. This time you will have 1 hour to unravel it. If you determine the reply, simply shout it out loud and we’ll offer you your reward. You should reply appropriate in your first strive although. Good luck!”

It did not take lengthy earlier than Mark solved half one, nicely earlier than the half-hour. So he rang the bell. They unlocked the door and Mark entered the room, noticed the desk and briefly noticed some giant rectangular plate on it. But simply inside milliseconds after the door received closed behind him, the half one of many puzzle abruptly made sense.

Being Mark, he managed to determine it out in fact and shouted the reply with nice pleasure (“they actually know me, these guys” he thought to himself) and received his reward. But it wasn’t too simple.

Can you inform me what Mark shouted?
