Write a functioin in C++ and follow the instruction, details would be really helpful

Node* deletelast(int). Given an int argument, this function deletes the last occurrence of the element, and returns a pointer to the deleted node. It does not affect the order of anything else. Thus, on deletelast (42) in the list 7 42 101 42 50 3, we get 7 42 101 50 3. (The usual delete would result in 7 101 42 50 3.)
