Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list. A Computer Science portal for geeks. Implemented it using stack - One of the best solution in C++. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. c++. Note: The flattened list will be printed using the bottom pointer instead of next pointer. 0. Given a nested list of integers, implement an iterator to flatten it. For example, given the list [[1,1],2,[1,1]], by calling next repeatedly until hasNext returns false, the order of elements returned by next should be: [1,1,2,1,1]. Flatten Nested List Iterator. Flatten Nested List Iterator 20 April, 2019. Stack, Design. A Computer Science portal for geeks. Medium. Suppose we have a nested list of integers; we have to implement an iterator to flatten it. Each element is either an integer, or a list – whose elements may also be integers or other lists. This is a brute force approach to obtaining a flat list by picking every element from the list of lists and putting it in a 1D list. Given a nested list of integers, implement an iterator to flatten it. The code is intuitive as shown below and works for both regular and irregular lists of lists: New. Each element is either an integer, or a list -- whose elements may also be integers or other lists. The elements of that list may also be integers or other lists. view: Flatten Nested List Iterator 题目描述. Each element is either an integer, or a list – whose elements may also be integers or other lists. 23. Runtime: 60 ms, faster than 92.00% of Python3, pure generator w/o intermediate list. Flatten Nested List Iterator Solution /** * // This is the interface that allows for creating nested lists. Flatten Nested List Iterator in Python. Flatten Nested List Iterator. It was a Saturday. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 2: It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview … Hot Newest to Oldest Most Votes. (ii) a bottom pointer to a linked list where this node is head. Java Solution 1 Given a nested list of integers, implement an iterator to flatten it. Flatten the Link List such that all the nodes appear in a single level while maintaining the sorted order. You have to know that chain only joins together the iterables passed as parameters, and the * causes the top-level list to be expanded into parameters, so chain joins together all those iterables, but doesn't descend further. Flatten Nested List Iterator. The * is the tricky thing that makes chain less straightforward than the list comprehension. Python Server Side Programming Programming. * // You should not implement it, or speculate about its implementation * public interface NestedInteger { * * // @return true if this NestedInteger holds a single integer, rather than a nested list. Flatten List of Lists Using Nested for Loops. Example 1: Given the list [[1,1],2,[1,1]], By calling next repeatedly until hasNext returns false, the order of elements returned by next should be: [1,1,2,1,1].
