This requires scanning the list to find the node where node.next == list.last.

WebLinked lists hold two main pieces of information (the value and pointer) per node. This means that the amount of data stored increases linearly with the number of nodes in the list. Therefore, the space complexity of the linked list is linear: \begin {array} {c}&&\text {Space - O (n)} \end {array}. Space - O (n). WebJul 6, 2024 · Traversal of a linked list has time complexity O ( n). So to provide O ( 1) insertion and deletion at both head and tail requires a method to look up the next or previous node in O ( 1) time, respectively. To illustrate: Let's say you have a forward singly linked list. To remove the tail node, you need to find it, which usually takes O ( n) time.
