LeetCode: 341. Flatten Nested List Iterator
Making a new list is an easy solution to implement with recursion. class NestedIterator: def __init__(self, nestedList: [NestedInteger]): self.res = [] self._flattener(nestedList) self.ptr = 0 def _flattener(self, nestedList): for nl in nestedList: if nl.isInteger(): self.res.append(nl.getInteger()) else: self._flattener(nl.getList()) def next(self) -> int: ret = self.res[self.ptr] self.ptr += 1..
