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...
您可以假设除了数字 0 之外,这两个数都不会以 0开头。 Give two non-empty linked lists to represent two non-negative integers. Among them, their respective digits are stored in reverse order, and each node of them can only store one digit. If we add these two numbers together, we will ret...
