numpy-free Interview Questions

Reported as a Qube Research & Technologies interview question, this problem challenges your understanding of fundamental machine learning algorithms by requiring you to implement K-Nearest Neighbors (KNN) classification entirely from scratch. You'll be provided with training data and test data, and your goal is to predict the labels for the test set without relying on any pre-built KNN libraries. This task assesses your ability to translate algorithmic principles into code, including distance calculations and majority voting for classification. It's a crucial test for aspiring data scientists and ML engineers. The full problem and model solution require a subscription.
