Array Problem to assess medium difficulty Algo knowledge:

The problem involves testing whether you can optimize an
𝑂(𝑛^2) time complexity algorithm into an 𝑂(𝑛) solution. This typically requires identifying a more efficient approach, such as using hash maps, sliding windows, or prefix sums, depending on the context.

Data Structure Problem

A LeetCode medium-level problem that tests your ability to create an algorithm using a data structure capable of storing data as key-value pairs, where the keys are strings and the values are lists.
You must leverage these objects to solve a broader problem statement and then analyze the time and space complexity of your solution, explaining why it’s optimal.
