Rank Stories and Filter by Offset

Implement a function rank_story(offset: int) that fulfills the following requirements: There is a function call get_story() which returns a set of pairs like [[st1, 25], [st2, 99]], where each pair consists of a story name and its rank. The function must return at least 5 story names since get_story() might occasionally return only 1 or 2 results; thus, it is necessary to repeatedly call get_story() to gather enough data. For the same story name, if returned multiple times, the rankings must be accumulated. Only keep stories with a ranking greater than the input offset. The returned results should be sorted in descending order based on ranking. Example Input 50
