Challenge 'One Function'

[arthur]

hi, i think i know how to solve this one
this function seems to run on 32-bits machine, am i right?

[CodeX]

is this the one I made? If so I think you'll find its x86-64, out of curiosity where about is it on the map?

Thanks, CodeX
i got it now
you can get it from here /Maeda Path/Number Theory/One Function

[CodeX]

Thanks, time to crack on with Number Theory

Hello,
I just ran the function and I got *****************,
but that's not the answer.
Am I missing something?

[CodeX]

yep

[dayepa]

I got it, thanks

I'm having lots of fun with this challenge... only not really

My disassembling attempts all seem to fail on the bytes "32 22" in the second half of the code... tried many different options. And even without that, trying to re-assemble this code is a pain. Which might be because it was never disassembled correctly.

Gah!

[AMindForeverVoyaging]

So, which tool are people using for the disassembly? I have tried:

-IDA (the 5.0 freeware version)
-debug.exe under Windows XP
-WinDbg under Windows 7
-objdump under Linux
-ndisasm

All to no avail.

[CodeX]

I think I used ndisasm to reverse the code to make sure everything was fine, but I made the function using GCC - there's more than one way to solve this :p

I have written a C program which does the same as the given function. I am getting a 17-digit number as the result (apparently like dayepa). This is however not accepted. What am I missing?

[Redford]

Try to 'decode' this number Answer is a word (or two, I don't remember)

[SemmZemm]

I'm getting 19-digit number (if decimal) Am I wrong somewhere? Could someone say me what's wrong?

[CodeX]

The function should be returning a 17 digit decimal, there's more than one way to interpret the code
