Solution: Maximum Performance of a Team

Explore how to maximize the performance of a team by selecting up to k engineers using the Top K Elements pattern combined with a greedy approach. Understand sorting by efficiency, managing speeds with a min-heap, and calculating maximum performance while considering constraints and time complexity.

Statement

You are given two integers, n and k, and two integer arrays, speed and efficiency, both of length n. There are n engineers numbered from 1 to n. The value speed[i] represents the speed of the i-th engineer, and efficiency[i] represents their efficiency.

To form a team with the maximum performance, you need to select at most k different engineers from the n engineers.

The performance of a team is calculated as follows:

The sum of the selected engineers’ speeds ×\times the minimum efficiency among the selected engineers

Return the maximum performance of the team. As the result can be a very large number, return it modulo (109+7)(10^9 + 7) ...
