A linked list is a collection of items where each item points to the next one in the list. Because of this structure, linked lists are very slow when searching for an item at a particular index. An array, by comparison, has quickgets when searching for an index, but a linked list mus...
Circular Linked List Algorithm - Learn about the Circular Linked List Algorithm, its structure, applications, and implementation details in data structures.
In order to avoid the linear cost of insertion and deletion, we need to ensure that the list is not stored contiguously, since otherwise entire parts of the list will need to be moved. èThe linked list: The linked list consists of a series of nodes, which arenot necessarily adjacentin ...
Optimized linked list structureRadix SortThe attribute reduction algorithm of radix sort to integer digit sequence table is not ideal. In this paper, based on how integers is stored in computer memory, low and high storage mode is designed for the solving algorithm of U/C chain structure of a...

8.1 -Lower bounds on sorting - Yes. Basic knowledge. May be asked in a Google interview (though unlikely, I know of a case it happened in before). 8.2 -Counting sort - Need-to-know in detail. It comes up in disguised forms.

Reverse a Linked List algorithm: a temp to store previous node, pointing to that in iterator class ReverseList{ public List reverse(List l){ Node firstNode = l.getFirst(); Node temp = firstNode.next; firstNode.next = null; if(l == null || l.isEmpty) throw new NotValidException()...

All inputs are consist of lowercase letters a-z. The values of words are distinct. 【Linked List Cycle II】Given a linked list, return the node where the cycle begins. If there is no cycle, return null. To represent a cycle in the given linked list, we use an integer pos which repr...
