Swap Two Nodes in Linked List Given a linked list and two values v1 and v2. Swap the two nodes in the linked list with values v1 and v2. It's guaranteed there is no duplicate values in the linked list. If v1 or v2 does not exist in the given linked list, do nothing. Notice ...

24. Swap Nodes in Pairs Given a linked list, swap every two adjacent nodes and return its head. You may not modify the values in the list's nodes, only nodes itself may be changed. Example: Given 1->2->3->4, you should return the list as 2->1->4->3. ...
每日算法之二十二:Swap Nodes in Pairs Given a linked list, swap every two adjacent nodes and return its head. For example, Given1->2->3->4, you should return the list as2->1->4->3. Your algorithm should use only constant space. You may not...
Reverse Nodes in k-Group Given a linked list, reverse the nodes of a linked list k at a time and return its modified list. If the number of nodes is not a multiple of k then left-out nodes in the end should remain as it is. ...

- Data structures: Several data structures, such as linked lists and binary trees, may require swapping elements or pointers tomaintain their integrity and perform specific operations efficiently. In conclusion, swap functions are a crucial part of programming, as they simplify the swapping process an...
