Still easy. But the Gandalf the Grey impersonator is not ready:
|
||||
>But use only _main()_, and do not use _math.h_ nor predefined stuff at all. But wait, there are some more rules: This
|
||||
work should reflect the extraordinary mind of Matti Nykänen,
|
||||
the all-time best [ski jumper](https://en.wikipedia.org/wiki/Matti_Nyk%C3%A4nen) and
|
||||
[amateur philosopher](http://telefinn.blogspot.com/2011/11/matti-nykanen-quotes.html), who passed away on fourth of

### Oh boys.

> But use only `main()`, and do not use `math.h` nor predefined stuff at all.
|
||||
But wait, there are more rules: This work should reflect the extraordinary mind
|
||||
of Matti Nykänen, the all-time best [ski
|
||||
jumper](https://en.wikipedia.org/wiki/Matti_Nyk%C3%A4nen) and [amateur

|

who passed away on fourth of February 2019.
|
||||
|
||||
So, I followed the rules given by Gandalf the White and the Judges of IOCCC. Output of `iocccsize`,
|
||||
using the [2019 version of iocccsize](https://www.ioccc.org/2019/iocccsize.c), is carefully selected.
|
||||
For the sake of clarity, I used single letter variables in the code. I also avoided unnecessary use of functions.
|
||||
Like a tripundra, this program has three levels. In order to reveal all of them, you have to compile this program
|
||||
on three consecutive days.
|
||||
### Oh boys:
|
||||
|
||||
As this is a contest for obfuscated code, the program does not perform unnecessary checks, but either fails or gets
|
||||
stuck if invoked erroneously. The program is invoked in this way: ./prog `<integer>` `<file>` in where `<integer>` is
|
||||
224, 256, 384, 512 or even 1024. Yes, I know 1024 is not a supported length of output, but as I said, the program does
|
||||
not validate its input in any way. These same parameters should be given in calculating a Fibonacci sequence or prime
|
||||
numbers. *Please note that maximum file size is one gigabyte.*

This code has some jumping too. I used some `goto`s instead of `longjmp()`. Some Finnish ski jumping sites are
|

used as labels, however, there is `lahti` instead of <tt style="font-family: Monaco, Courier New, monospace;font-size:
