nsert and Delete by CodeChum Admin A linked list with $7$ nodes is already defined in the code editor with the following elements: $5->3>22->100->-10->55->-7$ Your task is to complete four functions$/$methods: $$ Printing of the linked list function$/$method: You will traverse the linked list given the head node, and print in the similar format below. Note the lack of $->$ in the last element: $5322100->-10->55->-7$ Adding a node: The new element will be at the tail of the linked list, then, return the newly created node. $$ Insert at position: Given the dummy head, a new value, and the position, add the element at that position starting from the real head. $$ Delete at position: Similar to inserting at position but deleting at that position instead. Note that the functions to be implemented are commented on with "Implement me$!"$
