Knapsack Collection

Limits 1s, 512 MB

Gerald’s job is to welcome the teams for this year’s NWERC at the airport in Linköping. One of his duties is to stand at the luggage carousel and collect all the knapsacks that the teams are bringing. Gerald is a lazy person, so he just stands at the same position of the carousel and waits for bags to pass by so he can pick them up.
