Solution: High Five

Explore how to implement a hash map-based solution to compute the top five average scores for each student from a list of scores. Understand how to organize data efficiently using dictionaries, calculate averages by sorting scores, and handle constraints typical in coding interviews. This lesson helps you master pattern-based approaches to data aggregation problems, improving your problem-solving skills for technical interviews.

Statement

You are given a list of scores for multiple students, represented as items, where items[i]=[IDi,scorei]items[i] = [ID_i, score_i] ...
