You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers do not contain any leading zero, exc...
The number of nodes in each linked list is in the range[1, 100]. 0 <= Node.val <= 9 It is guaranteed that the list represents a number that does not have leading zeros. Ideas: use a pre (init: 0) to add into the curSum. Rember to check the pre after adding everything, beca...

next: a pointer to the next node in the list, ornullif it is the last node of the list. For example, the polynomial5x3 + 4x - 7is represented by the polynomial linked list illustrated below: The polynomial linked list must be in its standard form: the polynomial must be in strictly ...
Apply function to every item of iterable and return a list of the results. If additional iterable arguments are passed, function must take that many arguments and is applied to the items from all iterables in parallel. If one iterable is shorter than another it is assumed to be extended ...
