Minimum Cells to Bridge a Magic Grid
Company: Apple
Role: Software Engineer
Category: Coding & Algorithms
Difficulty: hard
Interview Round: Technical Screen
Overview: This question evaluates proficiency in graph traversal and shortest-path optimization within a 2D grid, testing the ability to find minimum-cost connectivity under constraints. It assesses practical application of BFS-based algorithms, including 0-1 BFS or Dijkstra's variant, commonly used to gauge depth of knowledge in graph theory and matrix traversal at a hard difficulty level.
