Time Complexity Analysis of Linked List - OpenGenus IQ: Computing

NettetIn a singly linked list you can add elements at both ends in constant time, and also remove the first element in constant time. In a doubly linked list, you can also remove the last element in constant time. However, indexing is very expensive . To find an element at a given index you need to traverse the list.

Hence, the worst time complexity is O (n) as the worst case is when all elements of the list need to be traversed. For example, let us consider the linked list: estimated monthly deposits

"Nettet6. jul. 2024 · As mentioned above, a strong point for choosing a ( doubly) linked list is constant time random insertion ( and deletion ). However, to get that time complexity, some form of reference to the relevant node needs to be handed out. This is usually done by wrapping it inside a LinkedListEnumerator. Doing this allows for: " - Linked list add time complexity
