How do I practice coding and algorithm questions?

Use PracHub's coding console to write, test, and debug your solutions in Python or JavaScript. View hints, test against sample inputs, and compare with official solutions.

What difficulty level is this coding question?

This is a medium difficulty Coding & Algorithms question, commonly asked during Onsite rounds at Uber.

What role is this question designed for?

This question is commonly asked for Software Engineer candidates at Uber during technical interviews.

Shortest Path in a Grid with Blocked Cells

Quick Overview

This question tests a candidate's practical grasp of graph traversal algorithms applied to 2D grid problems, specifically BFS for unweighted shortest-path search. It is a standard coding interview problem that assesses the ability to model spatial constraints, handle edge cases like disconnected graphs, and reason about time and space complexity at scale.
