Program to create a copy of a doubly linked list with an arbit pointer.

• Traverse the original list and create a new node for each node in the list.

• Store the mapping of original node to the new node in a hash table.

• Traverse the original list again and set the next and arbit pointers of the new nodes.

• Return the head of the new list.

Implement functionality for online test with timer and handle power failure scenarios

• Create a timer function to track the time

• Store the start time and end time of the test

• Implement a backup system to save progress in case of power failure

• Use a database to store test data and progress

• Handle edge cases like internet connectivity issues

A recursive function to check if a number is prime or not.

• Create a function that takes a number as input.

• Check if the number is less than 2, return false.

• Check if the number is 2, return true.

• Check if the number is divisible by any number less than it, return false.

• If none of the above conditions are met, call the function recursively with the number minus 1.

To reverse a linked list, we need to traverse the list and change the direction of the pointers.

• Create three pointers: prev, curr, and next

• Initialize prev to null, curr to head of the linked list, and next to null

• Traverse the list and change the direction of the pointers: next = curr.next; curr.next = prev; prev = curr; curr = next;

• Set the new head of the linked list to prev

It is not possible to stop man in the middle attack over an insecure communication line without using any kind of encryption.

• Without encryption, the communication line is inherently insecure and vulnerable to man-in-the-middle attacks.

• One possible solution is to use a secure communication line, such as a VPN or a dedicated private network.

• Another solution is to use digital signatures to verify the authenticity of the c...read more

HTTP is unsecured while HTTPS is secured with SSL/TLS encryption.

• HTTP stands for Hypertext Transfer Protocol while HTTPS stands for Hypertext Transfer Protocol Secure.

• HTTP operates on port 80 while HTTPS operates on port 443.

• HTTP is unencrypted while HTTPS is encrypted with SSL/TLS.

• HTTPS provides authentication and data integrity while HTTP does not.

• HTTPS is used for secure online transactions such as online banking, e

Heap and stack memory are two types of memory allocation in a program. Local variables are stored in stack memory. Memory tables are used to track memory allocation.

• Heap memory is used for dynamic memory allocation, while stack memory is used for static memory allocation.

• Local variables are stored in stack memory and are only accessible within the scope of the function they are declared in.

• Memory tables are used to kee...read more
