Feature #5: Top Brokers

Description

The company is doing performance evaluations. Each broker’s increments will be decided based on their level of activity throughout the last quarter. Each broker is assigned a unique ID that can be used to track their progress. Currently, this information is managed using an array. Every time a broker completes a trade, their ID is inserted into this array. Now, the company wants to promote its top k brokers. We have to implement a functionality that will automatically output the top k performers at the end of a quarter.

We’ll be provided with an array of integers representing the brokers’ IDs. Our task is to determine the top k most active brokers based on the number of times their ID occurs in the array.
