Easy data structure and algorithm practice puzzle.
Given a list of names, their scores, and k, return the names of the top k scorers, highest first. If two tie, keep the one that comes first in the list. Sort the positions by score from high to low, take the first k, and look up each name.
Solve it three ways: snap the jigsaw pieces together, fill in the blanks, or type it from scratch against the tests. This one is free.
Every line of the solution comes with a note explaining why it is there, and a step by step replay shows the code running. At level 3, where you type it yourself, you can ask for an AI mock interview on this problem that ends with a hiring manager's scorecard.
Then grow it into a real project with the Software Engineer button: this puzzle becomes the Match Calibrator, a pipeline you can run and download. See every Software Engineer project.
