WebMar 21, 2024 · A linked list is a linear data structure, in which the elements are not stored at contiguous memory locations. The elements in a linked list are linked using pointers as shown in the below image: In simple … WebOne possibility is writing a doubly-linked list class: add an extra pointer to each node, pointing at the previous node. Then, you can define additional operators on your iterators like --, and maybe even better, you can make insert_before and remove simple and efficient. The cost is that the list takes more space in memory. WebDec 25, 2024 · It doesn't really make sense to copy a node and all its descendants. Even if you wanted that behavior, this implementation is buggy. It removes all the previous links, so that you've got a singly linked list that pretends to be a double linked list. Iterator.h. Your iterator class is not quite right. It doesn't work as an end iterator. tiro cutting tools
