Riga is another beginner Reverse Engineering Challenge. Ghidra is a good tool to get started with disassembly and some RE challenges can be solved using Ghidra alone (no gdb required). The sources are included as sources.zip.enc... solve the challenge, get the flag, view the sources used to create the challenge if you are interested. Good Luck!

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

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