Nice challenge! Hint: learning Bruteforce and write python to deal with (idea quite same as Recklinghausen but harder).

Thank you author for an interesting challenge

You're welcome :-)

I am starting learn reverse. I have finished this chall for two days , It's great Thanks you very much

Glad you liked it, thanks for the feedback. Check out www.godbolt.org and www.dogbolt.org also

Does it match the description of the problem to solve it? please know let me know

I don't understand your question.

does it only use ghidra, or is there something else?

You can use gdb if you want to step through the debugger, or you can use IDA Pro if you have it, or you can use Radare2 if you know some assembly language; you can use lots of different approaches to solve this. Good Luck.

😂😂😂😂

I think perhaps someone use python should know that the ^ method is less priorer than the + - operator，it took me a long time
