This C Program implements doubly linked list using singly linked list. It makes use of 2 pointers, one points at the current node, other points at the head. When user requests to move back, the pointer from head travels to a previous node of the current pointer. The pointer to previous ...
(a) one will be a dynamically allocated array of object pointers, as we saw in the coding example of section 1.6, program #5 (b) the other will be a singly linked list, based on the coding example of section 3.1, program #7, but with two modifications: (i) the list will maintain ...

When implementing some data structures, such as list.inline functionFeaturesEquivalent to writing the contents of the inline function at the call of the inline function; It is equivalent to directly execute the function body without executing the steps of entering the function; Equivalent to a macro...
So, as we can see above, the pointer ‘ptr’ now contains address of a newly created node. If the linked list is empty and first node is created then it is also known as head node. Once a node is created, then it can be assigned the value (that it is created to hold) and its...

Using C++, write a code snippet to swap two adjacent elements by adjusting only the links (and not the data) and using a singly linked list. a. Write the definitions of the class circularLinkedList and its member functions. (Yo...
Given a singly linked list, return a random node’s value from the linked list. Each node must have the same probability of being chosen. Follow up: What if the linked list is extremely large and its length is unknown to you? Could you solve this efficiently without using extra space?
