Given a nested list of integers, return the sum of all integers in the list weighted by their depth. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Given the list [[1,1],2,[1,1]], return 10. (four 1's at dept...

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。
I am facing a number of errors in my Python code while referencing a leaf in a nested list. ---YANG---: list endpoints {key device;leaf device {type leafref {path "/ncs:devices/ncs:device/ncs:name";}}list intf {key intf_id;leaf intf_id {type string;} } } --...
MATLAB does not use the term "list" for any data class, although it does refer to comma separated lists (but these are not data storage). If you want to store nested data, then you need to learn about cell arrays , which are basically like lists in Python. There is one major differe...
