Problem: C Implement doubly linked list using dummy node with following operations. 1. ins key_of_y key_of_x /* (insert command) Insert node x after node y. First search node y using a key value. If node y is found then insert node x after node y. Otherwise insert node x after dummy node. */ 2. del key_of_x (remove command) /* Search a node x using a key value then delete it from the list if found. 3. sch search_key (search command) /* Search whole linked list against a key number. 4. shw (showall command) /* Traverse whole linked list and print all key values. */ 5. еxt (exit command) /* Exit from the program. Sample input ins 3 1 ins 1 2 Sample output INSERT after dummy node. INSERT after 1. ins 1 3 INSERT after 1. ins 2 4 INSERT after 2. ins 5 0 ins 0 2 shw INSERT after dummy node. INSERT after 0. 0 213 24 Node with key value 2 is DELETED. Node with key value 2 is DELETED. DELETE not possible. Node with key value 0 is DELETED. 134 del 2 del 2 del 2 del 0 shw sch 1 Node with key value 1 is FOUNDED. Not FOUND. sch 2 ext
