I've never read this chapter, to be honest, but what I know is that you need a basic grasp of probability in interviews because there's a good chance they may come up. That said, as long as you know basic probability concepts and practice on probability-related interview problems (there...

the traditional algorithm is low in efficiency; according to the algorithm, in adoption of a mode of combining the doubly linked list and the hash table, the starting node and the ending node of a tree can be rapidly queried; and addition O (1), deletion O (1) and query O (n) can...
1.Mark all nodes with a cost and a parent (i.e. in an array). 2.The source node has a cost of 0 and all other node has cost of infinity. 3.While there is an unvisited node in the graph do pick the node with the smallest cost, mark it as visited. update all its unvisited...
2.3. Simple Linked Lists 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 are...

It is type of linear data structure. It follows LIFO (Last In First Out) property. It has only one pointer TOP that points the last or top most element of Stack. Insertion and Deletion in stack can only be done from top only. Insertion in stack is also known as a PUSH operation. ...
Kafka uses a time wheel to implement a delay queue, because the bottom layer is that the addition and deletion of tasks is based on a linked list, which is O(1) time complexity and meets the requirements of high performance; For delayed tasks with a large time span, Kafka introduces a ...
