Graphs have vertices (nodes) connected by edges: G = (V, E) 开始学习

|
|
|
A graph that contains a cycle is a tree 开始学习
|
|
|
|
|
Properties of free trees: 开始学习
|
|
Any two vertices in a free tree are connected by a unique path, If a single edge is removed from a free tree, it becomes disconnected; If any edge is added to a free tree, it becomes a graph with a cycle (no longer a tree)

A binary tree T is a structure defined on a finite set of nodes that either - contains no nodes, or - is composed of three disjoint sets of nodes: 开始学习
|
|
A binary tree called right subtree, A root node, A binary tree called left subtree
|

Consider the original array 17, 8, 12, 4, 26. How many comparisons are needed to construct the BST on the original array? 开始学习
|
|
|
|
|
In binary tree sort, we first construct the BST and then we perform _______ traversal to get the sorted order. 开始学习
|
|
|
|
|
What is the worst case time complexity of the binary tree sort? 开始学习
|
|
|
|
|
What is the best case time complexity of the binary tree sort? 开始学习
|
|
|
|
|
Binary tree sort is an in-place sorting algorithm. 开始学习
|

|
Which of the following sorting algorithms can be considered as improvement to the binary tree sort? 开始学习
|
|

|
What is the time complexity to count the number of elements in the linked list? 开始学习
|
|
|
|
|
Which of the following points is/are true about Linked List data structure when it is compared with array 开始学习
|
|
It is easy to insert and delete elements in Linked List; Random access is not allowed in a typical implementation of Linked Lists
|
|
|
Which of the following sorting algorithms can be used to sort a random linked list with minimum time complexity? 开始学习
|
|
|
|
|
In the worst case, the number of comparisons needed to search a singly linked list of length n for a given element is 开始学习
|
|
|
|
|
What are the time complexities of finding 8th element from beginning and 8th element from end in a singly linked list? Let n be the number of nodes in linked list, you may assume that n > 8. 开始学习
|
|
|
|
|
Why do we impose restrictions like - root property is black - every leaf is black - children of red node are black - all leaves have same black 开始学习
|
|
to get logarithm time complexity
|
|
|
What are the operations that could be performed in O(logn) time complexity by red-black tree? 开始学习
|
|
insertion, deletion, finding predecessor, successor
|
|
|
Which of the following is an application of Red-black trees and why? 开始学习
|
|
can be used in process schedulers, maps, sets
|
|
|
How can you save memory when storing color information in Red-Black tree? 开始学习
|
|
using least significant bit of one of the pointers in the node for color information
|
|
|
What is the special property of red-black trees and what root should always be? 开始学习
|
|
a color which is either red or black and root should always be black color only
|
|
|
Which of the following points is/are true about Linked List data structure when it is compared with array 开始学习
|
|
The size of array has to be pre-decided, linked lists can change their size any time; Arrays have better cache locality that can make them better in terms of performance.
