Access each element of the sublist using a nested loop and append that element to flat_list. Example 3: Using itertools package import itertools my_list = [[1], [2, 3], [4, 5, 6, 7]] flat_list = list(itertools.chain(*my_list)) print(flat_list) Run Code Output [1, 2, 3...

https://leetcode.com/problems/flatten-nested-list-iterator/ 展平嵌套的list。 从调用的方式来看,总会调用到最后,所以在构造函数中递归展开所有的数放到一位数组中。 另一种方式是把nested list压到栈中,需要的时候再从栈中拿。 注意需要调用注释中的isInteger(),getInteger()和getList()三个方法。

Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Input: [[1,1],2,[1,1]] Output: [1,1,2,1,1] ...

The code to flatten the matrix is concise, but it may not be so intuitive to understand how it works. On the other hand, if you usedforloops to flatten the same matrix, then your code would be much more straightforward to understand: ...
