Graphs pattern
Cheapest Flights Within K Stops
Given flights as directed weighted edges between cities, a source, a destination, and an integer k, return the cheapest total price to travel from source to destination using at most k intermediate stops, or -1 if no such route exists. Watch it run step by step, then write your own pseudocode and get it checked by AI.
