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。

Flatten List of Lists Usingnumpy(concatenate() and flat()) Numpyoffers common operations which include concatenating regular 2D arrays row-wise or column-wise. We are also using theflatattribute to get a 1D iterator over the array in order to achieve our goal. However, this approach is relati...
