Day 16: Exceptions – String to Integer(30 Days of Code)

Read a string, S, and print its integer value; if cannot be converted to an integer, print Bad String.
Note: You must use the String-to-Integer and exception handling constructs built into your submission language. If you attempt to use loops/conditional statements, you will get a 0 score.

Day 15: Linked List (30 Days of Code)

Complete the insert function in your editor so that it creates a new Node (pass data as the Node constructor argument) and inserts it at the tail of the linked list referenced by the head parameter. Once the new node is added, return the reference to the head node.
Note: The head argument is null for an empty list.
