Design and implement a class ToDoList. An object of this class—let’s call it a to-do list—is a collection of strings that describe tasks a user wants to accomplish. Strings on this list appear in order, one after the other, just as they would had you written a list of tasks on paper. In other words, each string has a position on the list beginning with 1, as in the following example:
The list should be as long as the user desires. Give the to-do list the following behaviors:
• add—Add a new task to the end of the list
• remove—Remove and return the first task from the list
• replace—Replace and return a particular task, designated by its number, with a new task
• getCurrentSize—Return the current number of tasks on the list
• isEmpty—Return true if the list is empty or false if it is not
• clear—Erase all tasks from the list
