IOI 2012 Odometer. Getting WA on wcipeg.com [help]
Автор LaKsHiTh_, история, 4 года назад, По-английски

I tried the Pebbling odometer task of IOI 2012. I wrote an output for the subtask 1 and uploaded it to the wcipeg judge. But i got WA. Then i downloaded the input data and tried them manually. They gave the correct answer. Then i uploaded the official Solution given by ioinformatics.org. Still it's WA. Does anyone know why this happens.

My solution:

left
rr: 
pebble r
halt
ll:
pebble l
halt
r:
get
right
right
move
jump ll
l:
get
left

move
jump rr

I have found what's wrong. Official statement did not contain this but PEG judge had this:

Your submission must contain solutions for all the subtasks, and can have a maximum size of 25 MiB. The odometer programs for each subtask must be preceded by the line [SUBTASK #], where # is the subtask number.

while the Official statement said

You have to submit exactly one file per subtask
