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...
力扣leetcode-cn.com/problems/add-two-numbers/ Notes 1. Addingdummyhead to align the for-cycle 2. Considering the different length, use zero value to represent the empty node 3. Considering the special case such as 1+99, which produces a longer list 4. Useunsigned charto save memory,...
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...

ListNode*head,*p,*q;head=newListNode;p=head;//assume that the singly-linked list is 0->1->2for(int i=0;i<3;++i){q=newListNode(i);p->next=q;p=p->next;} 解题思路: 本题实际上就是大数加法。用一个变量carry表示进位,然后对应的位数相加的时候要加上进位,这个和记为oneSum。那么carry...

[LintCode/LeetCode] Add Two Numbers Problem You have two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1's digit is at the head of the list. Write a function that adds the two numbers and returns ...
This leetcode's problem is a favorite question of coding interviews. The data structure we are going to work with is Singly LinkedList. It's super fun. Note: We are not going to use the inbuilt LinkedList class of C# because that is a doubly linked list....
