Understanding the Nested Array Generator Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given a multi-dimensional array of integers, return a generator object which yields integers in the same order as inorder traversal. A multi-dimensional array is a recursive data structure that contains both integers and other multi-dimensional arrays. inorder traversal iterates over each array from left to right, yielding any integers it encounters or applying inorder traversal to any arrays it encounters.

Get real-time assistance for Nested Array Generator problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
arr = [[[6]],[1,3],[]][6,1,3]const generator = inorderTraversal(arr); generator.next().value; // 6 generator.next().value; // 1 generator.next().value; // 3 generator.next().done; // true
arr = [][]There are no integers so the generator doesn't yield anything.
