1. You are given a link based list with n number of elements . Select all true statements: Group of answer choices Best case access to an element is Θ(1) given a pointer to a suitable location in the list, running time for removing a node at that location is Θ(n) on average. worst case access to an element is Θ(n) given a pointer to a suitable location in the list, running time for inserting a node at that location is Θ(n) on average given a pointer to a suitable location in the list, running time for inserting a node at that location is Θ(1) on average 2. Consider the concept of the list data structure. Select all true statements about a list: Group of answer choices The number of elements currently stored is called the length of the list The element inside are ordered in the sense of sorted order A list is said to be empty when it contains no elements The end of the list is called the tail. The beginning of the list is called the head 3. Consider an array-based list implementation. Inserting a new element to the current position in which the current position is at the begenning of the array takes: Group of answer choices Θ(nlog(n)) time Θ(log(n)) time Θ(1) time Θ(n2) time Θ(n) time 4. True or False? In a linked list, the successive nodes in the list must occupy contiguous space in memory. Group of answer choices True False 5. What data structure is associated with the term LIFO? Group of answer choices a stack an array based list a queue a doubly linked list a singly linked list
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
1. You are given a link based list with n number of elements . Select all true statements:
Group of answer choices
Best case access to an element is Θ(1)
given a pointer to a suitable location in the list, running time for removing a node at that location is Θ(n) on average.
worst case access to an element is Θ(n)
given a pointer to a suitable location in the list, running time for inserting a node at that location is Θ(n) on average
given a pointer to a suitable location in the list, running time for inserting a node at that location is Θ(1) on average
2. Consider the concept of the list data structure. Select all true statements about a list:
Group of answer choices
The number of elements currently stored is called the length of the list
The element inside are ordered in the sense of sorted order
A list is said to be empty when it contains no elements
The end of the list is called the tail.
The beginning of the list is called the head
3. Consider an array-based list implementation. Inserting a new element to the current position in which the current position is at the begenning of the array takes:
Group of answer choices
Θ(nlog(n)) time
Θ(log(n)) time
Θ(1) time
Θ(n2) time
Θ(n) time
4. True or False? In a linked list, the successive nodes in the list must occupy contiguous space in memory.
