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...
Given two polynomial linked list heads,poly1andpoly2, add the polynomials together and returnthe head of the sum of the polynomials. PolyNodeformat: The input/output format is as a list ofnnodes, where each node is represented as its[coefficient, power]. For example, the polynomial5x3 + 4x...
Add the two numbers and return it as a linked list. You may assume the two numbers do not contain any leading zero, except the number 0 itself. 翻译 给定两个非空的链表,代表两个非负整数。这两个整数都是倒叙存储,要求返回一个链表,表示这两个整数的和。 样例 Input: (2 -> 4 -> 3) +...
