- C Programming language Part 1: You need to define a data structure for a doubly linked list and a binary search tree. Also, you need to implement the following functions: Insert Sorted LINKEDLIST insertSorted(LINKEDLIST head, int num): head points to the first node in the sorted linked list; num is a number to be inserted in in correct place in the linked list pointed at “head”. The linked list should be sorted after inserting “num”. This function returns the head of the modified head. BSTREE insert(BSTREE root, int num): root points to a node in a binary search tree; num is a number to be inserted in the tree rooted at “root”. This function returns the root of the modified tree. Find an element LINKEDLIST find(LINKEDLIST head,int num): head points to the first node of a linked list; num is a number to be searched for in the linked list started at “head”. This function returns a pointer to the node containing “num” or NULL if num is not found BSTREE find(BSTREE root,int…The definition of linked list is given as follows: struct Node { ElementType Element ; struct Node *Next ; } ; typedef struct Node *PtrToNode, *List, *Position; If L is head pointer of a linked list, then the data type of L should be ??Computer Science JAVA Write a program that maintains the names of your friends and relatives and thus serves as a friends list.

This class should contain a Binary Search Tree of names as a data field. (TreeNode Class BinarySearchTree Class FriendsList Class)
