Answer #1

Solution:

The answer will be an option,

(A) f

Explanation:

=>Given data structure is linked list representation of disjoint sets.

=>Head is pointer which is pointing to the first member of the linked list.

=>Tail is the pointer which is pointing to the last member of the linked list.

=>Each member contains a next pointer which is pointing to the next node/member.

=>"First member" of the linked list is called as "representative" of the set.

=>As the first member is "f" hence representative = f.

I have explained each and every part with the help of statements attached to it.

    implement a doubly-linked list in C. Each node in the linked list should contain a string, a pointer to the previous node (or NULL), and a pointer to the next node (or NULL). The nodes should be sorted by their strings. struct node_t { char* str; struct node_t* prev; struct node_t* next; } To maintain the doubly-linked list, you should keep a pointer to the head node of the list (or NULL if the list is empty), and a pointer...

    You implemented a stack as a singly linked list (you add at the head and remove from the head). Perform the following operations on the stack: push(50), push(90), push(30), push(53), push(52), pop(), push(51), pop(), pop(), push(100), and push(15). After all the operations are performed, draw the resulting linked list. Indicate which node is the top of the stack in the resulting linked list.

    Problem Statement This problem provides you with a linked list composed of node objects chained together via node pointers. Each node has a next pointer which points to the next node in the chain. The last node is identified by having a NULL (or nullptr) next pointer. The linked lists for this problem store string data. Your task: identify the longest string stored in the linked list. If two strings are of the same length, return the string that occurred...
