문제

Little Michael lives in a small country and likes to watch a TV music show which is emitted every Sunday afternoon. It presents the same songs every week and, according to votes, displays popularity list of those songs.

Michael played too long with his friend one Sunday and failed to see new popularity list. He was sad, but he soon realized that he would be able to at least partially reconstruct the popularity list next week. Apart from the positions of songs, a list contains information about change of positions of all songs with regard to their last week’s positions. More precisely, each song is given a mark indicating whether that song stayed at same position, gained or lost popularity since last week.

Write a program that will using given popularity list help Michael to determine one possible last week’s popularity list.
