EVEN OR ODD? (SPLIT NUMBERS INTO EVEN AND ODD.)

I liked that little challenge. After small optimization for cycles I've got 1580/60/39

Something that i thought was incredibly simple, turned out to be quite complex due to the nuances of the file structure, like everything being unsorted. Very cool.
Do name your hosts in english please. I kept getting confused whether dispari was odd or even, and putting in the wrong links.

@visualrob: General idea is to have an incrementing counter X from -100 up to 401, which covers the range of all possible test case numbers. Two empty files, 400 and 401 are created. The counter is compared and REPLed with all entries in the file - if a match is found, the REPLed EXA doesn't crash and writes to the end of either 400 or 401 depending on its parity.

When the whole file is read, the counter is incremented by 1 and a test is done if X < 401. This serves two purpose: first to differentiate 400 and 401, and secondly to crash the EXA when 401 is reached. GRAB X is then used and the test result between 400/401 tells it to link to the correct host output.

I used 123 lines of code and 2013 cycles. I almost never optimize for fewest lines of code. Well, unless I'm playing TIS-100 and I'm forced to. ;-) In real life, faster code almost always makes more sense than smaller code.

The PARI/DISPARI was no problem. If I can solve Zachtronics games, I can figure stuff like that out. ;-)

@flowflow: is there a way to look at your solution? It would be very instructive!

@RevengeFromMars: "leave no trace" means you have to leave everything as it was at the start. Since you start with the file 200 in the INBOX, you have to leave it there (otherwise people will know you meddled with it).

How many lines of code did it take?

PS: Sorry for "PARI" and "DISPARI", I didn't notice I left them in Italian :)

You can always use the SHOW GOAL button if in doubt about which files should end up where.

I figured it out - apparently I wasn't supposed to delete the original file? Isn't that "leaving a trace"?

I'm confused - I've done exactly as required, creating the even file in "pari" and the odd one in "dispari", no other files or EXAs remain, yet I'm not being credited with a win because "leave no trace" isn't checked. Am I supposed to put the two files somewhere else?

A little better in size: down to 62763/29/3.
