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...
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...

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....
We need to consider carry when calculating each digit and the situation where l1 and l2 may have different length. We will need to check the remaining of either l1 or l2 (depends on which one is longer). Finally, don't forget to add 1 more digit if the last digit we calculate exceeds...
Design a data structure that supports the following two operations: void addWord(word) bool search(word) search(word) can search a literal word or a regular expression string containing only letters a-z or .. A . means it can represent any one letter. ...

Once you have forked the repo, add your progam in the language folder in main branch, if there is no language folder, make one, then add into it. You can take a look to the Programming Language List in Wikipedia to create a new one for Hacktoberfest! 4. Ready, Steady, Go... ...
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 ...
