Consider a Double Linked List with just one node and then select the correct statement:
Step by step
Solved in 2 steps
- Consider a Double Linked List with just one node and then select the correct statement: a. Both the head and the tail points to each other b. The head and the tail point to the same node in the list c. The head points to the node but the tail points to null d. The tail points to the node but the head points to nullSuppose that you have a singly linked list with five nodes and with head reference. Then the statement head = head.next will remove the first node of the linked list? a) true b) falseSuppose x is a linked-list node and not the last node on the list. What is the effect of the following code fragment?x.next = x.next.next;
- Given a scenario where you need to efficiently insert elements at the beginning of a list, which type of linked list would be most suitable? Explain why.Consider the Double Linked List that is given below, where each box represents a ‘node’ type with two fields: integer data and a node type reference ‘next’ that points to the next node in the list. a) Write an algorithm to count all nodes that contain an odd number. b) Write an algorithm to print all nodes that contain an even number in the reverse direction of the list.Reverse a singly linked list by changing the pointers of the nodes. The datarepresented by the list should continue to remain in the same nodes of the originallist.For example, given a singly linked list START, as shown in Figure P6.9(a), the listneeds to be reversed, as shown in Figure P6.9(b), by manipulating the links alone.
- Write the code to delete a node in the middle of a list implemented as a linked list with the dummy node (see Exercise 3). Compare your answer with the answer to Exercise 3. Are they the same? What do you conclude? Does the dummy node simplify the operation on the list? How?In which of the following linked list there will be no beginning and ending? a. Depends on the Problem. b. Circular Linked List. c. Double Linked List. d. Single Linked List. Clear my choiceConsider a double linked list where ‘head’ points to the first node, and ‘tail’ points to the last node. Complete the following fragments of code to insert a node at the beginning of the list. public class insertFront(int data) { }
- Suppose there are two singly linked lists both of which intersect at some point and become a single linked list. The head or start pointers of both the lists are known, but the intersecting node is unknown. Also, the number of nodes in each of the list before they intersect are unknown and both the list may have it different. List1 may have n nodes before it reaches intersection point and List2 might have m nodes before it reaches intersection point where m and n may be m = n, m > n or m < n. Give an algorithm for finding the merging point. Hints: A brute force approach would be to compare every pointer in one list with every pointer in another list. But in this case the complexity would be O(mn)Consider a singly linked list where each node contains two fields – integerdata and node type pointer next. The head of the list and a value of the data isgiven. You have to find the node that contains the given data and delete thatnode. Data may occur at any position of the list including first or last. In caseof unavailability of the given data, you have to print a message.
