Quick Summary
Navigate a 2D grid from a starting point to a destination using designated transportation modes.
Paths are restricted to contiguous cells sharing the same mode identifier.
Identify the mode that minimizes total travel time, using lowest cost as a tiebreaker.
What This Tests
Modeling 2D grids as weighted graphs for pathfinding.
Implementing priority queue driven shortest path algorithms like Dijkstra.
Handling multi-criteria optimization with lexicographical tie-breaking.
Tracking traversal state and avoiding redundant visits efficiently.
