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...
