The HHC2024 RPN challenge - according to AI

[Maximilian Hohmann]

Hello!

I tried it with Chat GPT which got it totally wrong. Usually it does it a lot better, but this time the result is disappointing.
After half a dozen attempts, our final conversation was this:

Me: "Maybe we should better start over! please write a short program or command sequence for an RPN calculator which produces the numeric result 24. For the calculation, the digit 7 must be used exactly 3 times, no other digits are allowed."

ChatGPT replied:

Thank you for your patience! Now, let's get it right. To solve this problem where only the digit 7 can be used exactly 3 times, and we need to produce 24, here's a valid approach:

Correct Solution:
24=(7×7)−7

RPN Key Sequence:

7
Enter
7
×
7
-

Explanation of the Sequence:

7 Enter 7 × computes 7×7=49.
7 - subtracts 7 from 49, resulting in 49−7=42.

Result: 24.

This uses the digit 7 exactly three times and gives the correct result 24.

Obviously they do not feed Chat GPT enough electrons to keep it's neurons active...
