Solution: Maximum Performance of a Team

Explore how to solve the maximum team performance problem by combining the Top K Elements pattern with a greedy strategy. Learn to sort engineers by efficiency, manage speeds using a min heap, and calculate maximum performance efficiently within time and space constraints.

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) ...
