LeetCode 341 Flatten Nested List Iterator Input: [[1,1],2,[1,1]] Output: [1,1,2,1,1]

Can you explain how you would flatten this nested iterator?

Interviewer · 9:45 AM

I’ll use a stack and expand nested lists only when needed.

You · 9:46 AM

What is the time complexity if next is called repeatedly?

Hint AI

Use a stack initialized with the nested list in reverse. In hasNext(), keep expanding the top item until it is an integer. Then next() can safely pop and return it.

class NestedIterator: def __init__(self, nestedList): self.stack = nestedList[::-1] def hasNext(self): while self.stack: top = self.stack[-1] if top.isInteger(): return True self.stack.pop() self.stack.extend(top.getList()[::-1]) return False

I’d start by clarifying the scale and consistency requirements, then separate the API, queue, workers, and storage so each part can scale independently.
