USING DATA STRUCTURE STACK IN PYTHON PLEASE.

Please solve the following problem with programming using proper data structures. A similar application to the parentheses matching problem comes from hypertext markup language (HTML). In HTML, tags exist in both opening and closing forms and must be balanced to properly describe a web document. This very simple HTML document: Example title> head>

Hello, world body > html > is intended only to show the matching and nesting structure for tags in the language. Write a program that can check an HTML document for proper opening and closing tags. To simplify the problem, we suppose the opening and closing tags are provided in separate lines without indentation (shown in the green box on the right above). The Stack class should include the following methods: - push(item) function to add a new item to the stack - pop0 function to remove the top item from the stack - peek() to return the top item in the stack - is_empty0 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: - If the text line matches an opening tag (e.g.

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

), check whether the stack is emptyO: - 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
