The interview focused on core concepts of React, such as state management, hooks, and lifecycle methods, along with backend principles in Node.js, including API development and middleware. Additionally, they tested my understanding of Data Structures and Algorithms (DSA) with problems related to arrays, linked lists, and optimization techniques. The questions required both theoretical knowledge and practical problem-solving skills.
You are given a 2D grid of integers where:
0 represents an empty cell,
1 represents a fresh orange, and
2 represents a rotten orange.
Every minute, any rotten orange rots its adjacent fresh oranges (up, down, left, right). Write a function to determine the minimum time required for all fresh oranges to become rotten. If it is impossible to rot all oranges, return -1.
Tip 1: Focus on basic recursion.
Tip 2: Optimization.
