Provide tags and a correct Python 3 solution for this coding contest problem. Recently, Tokitsukaze found an interesting game. Tokitsukaze had n items at the beginning of this game. However, she thought there were too many items, so now she wants to discard m (1 ≤ m ≤ n) special items of them. These n items are marke...
