# What Is The Time Complexity Of Adding A Node At The End Of Single Linked List

1 [What is] the worst-case time complexity of adding to a singly-linked list after the tenth node with a size of at least ten. That specific task, adding an item immediately after node ten, is O (1) (a). That's because the time taken to do it is not affected by the list size at all. The time complexity for the Inserting at the end depends if you have the location of the last node, if you do, it would be O (1) other wise you will have to search through the linked list and the time complexity would jump to O (n).

Time Complexity: O (1), We have a pointer to the head and we can directly attach a node and change the pointer. So the Time complexity of inserting a node at the head position is O (1) as it does a constant amount of work. Auxiliary Space: O (1) Add a node after a given node: (5 steps process)

If you want to delete a specific element, the time complexity is O (n) (where n is the number of elements) because you have to find the element first. If you want to delete an element at a specific index i, the time complexity is O (i) because you have to follow the links from the beginning. Add a node to the end of the linked list: This takes linear time O (n) because unlike arrays in which you can access any index in constant time, you need to traverse through the entire linked list to reach the end and then add it. But, if you maintain a pointer to the tail of the list, this can also be done in O (1) time. From this article on time complexity of memory address, we known that to access a specific element, the time complexity is O (√N) where N is block of continuous elements being read. As Linked List elements are not contiguous, each element access incur a Time Complexity of O (√N). If you want to insert at the beginning of the list, you just make the new list head the node you want to insert, and link it to the previous list head. If you want to insert at the end of the list, you can also hold the end of the list as a pointer and insert a new node after it.

What is the time complexity of inserting a node into a linked list? Strictly speaking an insertion is simply O (1). The other answers mostly correctly state that the complexity is O (n) if you need to search for the position in which to insert the new node; but in most case a linked list is never used in a situation where a search is necessary. Answer: (A) Explanation: Finding the 8th element from the beginning of a singly linked list requires traversing the first 8 nodes of the list, which takes O (8) time, or simply O (1) time since it's a constant time operation. ANSWER:: QUESTION 9 :: What would be the time complexity to add a node at the end of singley linkedlist.if the pointer is initally pointing to the beginning. View the full answer Transcribed image text : Time Complexity: It is defined as the number of times a particular instruction set is executed rather than the total time taken. It is because the total time taken also depends on some external factors like the compiler used, the processor's speed, etc. Space Complexity: It is the total memory space required by the program for its execution.

What would be the asymptotic time complexity to add a node at the end of singly linked list, if the pointer is initially. O(n) (c) θ(n) (d) θ(1) LIVE Course for free. Rated by 1 million+ students. What would be the asymptotic time complexity to add a node at the end of singly linked list, if the pointer is initially pointing to the head. In the case of a linked list having n elements, we need to travel through every node of the list to add the element at the end of the list. Thus asymptotic time complexity is θ(n).

Explanation: Time complexity of inserting a new node at the head of the list is O (n) because you have to traverse through the list to find the tail node. READ: How did Nagini Recognise Harry?
