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.
