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 Technical Screen rounds at OpenAI.

What role is this question designed for?

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

Infection Spread Simulation with Death Threshold

Quick Overview

This question evaluates a candidate's ability to implement grid-based simulation with multi-state cellular automaton logic, testing practical application of BFS/iterative traversal and careful simultaneous state transitions. It falls within the Coding & Algorithms domain and assesses how well engineers handle complex rule sets, neighbor counting, and convergence detection on 2D grids.
