singly linked list java

Topic linksTitle Requirements:Given a singly linked list l: l0→l1→ ... →ln-1→lN,Reorder it to: l0→ln→l1→ln-1→l2→l N-2→ ...You must does this in-place without altering the nodes ' values.For example,Given {1,2,3,4} , reorder it to {1,4,2,3} .Just see the topic, the first idea came out as follows:　　The corresponding program is as follows:1 /**2 * Definition for

1. transpose one-way linked list (that is, reverse order. Pay attention to the boundary condition of the linked list and consider empty linked list ). # Include Struct listtype{Int data;Struct listtype * next;}; Typedef struct li

list. * struct ListNode {* int val; * ListNode *next; * * * class Solution {public: void deletenode (listnode* node) { node ->val = node->next->val; Node->next = Node->next->Next;} };Also, in C + +, pay attention to freeing up memory. You can add delete.There's something simpler. /* * * Definition for singly-linked

Today, starting with the data structure, the first thing to know is the linked list. I start with the creation of the list, I am accustomed to using Java, to start the introduction also use Java implementation Linked

The merge sort of the linked list (linklist merge sort)First of all, if there are two ordered (sorted) linked list ListNode *a, and ListNode *b, how to merge into an ordered list?ListNode * mergetwolists (ListNode *l1, ListNode *L2) {ListNode*head =NewListNode (-1); ListNode

Given a singly linked list l: l0→l1→ ... →ln-1→lN,Reorder it to: l0→ln→l1→ln-1→l2→l N-2→ ...You must does this in-place without altering the nodes ' values.For example,Given {1,2,3,4} , reorder it to {1,4,2,3} .Hide TagsLinked List If you use extra space, it is easy to implement, determine the middle position, th

Given A linked list, remove the nth node from the end of the list and return its head.For example, n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.Subscribe to see which c

Reverse a linked list from position m to N. Do it in-place and in One-pass.For example:Given 1->2->3->4->5->NULL , m = 2 and n = 4,Return 1->4->3->2->5->NULL .Note:Given m, n satisfy the following condition:1 ≤ m ≤ n ≤length of list.Big early in the morning to be linked to the list of abuse cry Ah, looked at others, th

Title: Sort A linked list in O (n log n) time using constant space complexity.Train of thought: Require time complexity O (NLOGN)Knowledge Points: Merge sort, link list find Midpoint methodDisadvantages of existence: the boundary condition is more consideration!!!/** * Leetcode Sort list Sort a

Topic linksTitle Requirements:Given A linked list, remove the nth node from the end of the list and return its head.For example, 1,2,3,4,52. 1,2,3,5.Note:Given n would always be valid.Try to do the in one pass.　　The conventional idea of this problem is to calculate the length of the linked

Sort a linked list in O(n log n) time using constant space complexity.Time complexity is O (NLOGN), you can think of merge sort, quick row, bucket sort.Idea: Using merge sort, the whole can be divided into two bodies, one, the construction of two sorted sub-linked list; second, the sub-

Given a sorted linked list, delete all duplicates such this each element appear only once.For example,Given 1->1->2 , return 1->2 .Given 1->1->2->3->3 , return 1->2->3 .Subscribe to see which companies asked this questionSolution: Set two pointers Curr and next point to the adjacent two nodes, scan from the back, (1) If the two nodes that point to the value are equal, delete the node that next points to, an

Finally, based on the contents of the stack into a path, note that we use the list of doubly linked li
