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。 1#"""2...
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] ...
