Create a Stack abstract data type The Stack class should include the following methods: push(item) function to add a new item to the stack pop() function to remove the top item from the stack peek() to return the top item in the stack is_empty() to test whether the stack is empty size() to tell the size (number of items) in the stack Create a html_checker function The function: Takes a string of HTML code as argument; Returns true if all tags are balanced; false if otherwise. Here is what the function should do: Create a new Stack object; Use the split() method of a string to split it into text lines; Create a loop to read the text lines, and for each text line: o If the text line matches an opening tag (e.g.

), add the tag name (e.g. h1) to the stack; o If the text line is ordinary content without a HTML tag, skip the line; o If the text line is a closing tag (e.g.

), check whether the stack is empty(): The HTML code is unbalanced if stack is currently empty; If not empty, use pop() to read and remove the top item from stack: The top item/tag matches the current closing tag, then the HTML code is balanced (true); Otherwise, the HTML code is unbalanced (false). Program Execution Create two variables, one with balanced HTML code and the other with unbalanced HTML code. Run the html_checker function with each of the two variables as argument to test the program.
