- The linked list is إختر أحد الخيارات: a. Array of nodes structure b. array of pointers each one point to node structure c. A link that points to another link d. a pointer that points to node structure أخلِ اختياريBelow you're given a Node class and a LinkedList class. You will implement a method for the LinkedList class named "delete48in148". That is, whenever there is a sequence of nodes with values 1, 4, 8, we delete the 4 and 8. For exCample, Before: 1 -> 4 -> 8 LAfter: 1 Before: 7 -> 1 -> 4 -> 8 -> 9 -> 4 -> 8 After: 7 -> 1 -> 9 -> 4 -> 8 Before: 7 -> 1 -> 4 -> 8 -> 4 -> 8 -> 4 -> 8 -> 9 After: 7 -> 1 -> 9 Note from the above example that, after deleting one instance of 48, there may be new instances of 148 formed. You must delete ALL of them. Requirement: Your implementation must be ITERATIVE (i.e., using a loop). You must NOT use recursion. Recursive solutions will NOT be given marks. import ... # No other import is allowed"Chu" "Bethany" "Daryl" next ull next next head "Brandon' next The above is a LinkedList. 1. If a node with the data, "Brandon" needs to be inserted between the node of "Bethany" and the node of "Daryl", which step of the following needs to be performed first? a. Update the value of the box, next in the Node with "Bethany" first. b. Assign the value of the box, next in the Node with "Brandon" first. Describe the reason of your choice.
