Web developers use html tags in angle brackets to format the text on web pages (see appendix c). write a method removetag that checks whether a given string starts with an apparent html tag (a character or word in angle brackets) and ends with a matching closing html tag (the same character or word preceded by the „\‟ character, all in angle brackets). if yes, the method removes both tags and returns the result; otherwise the method returns the original string unchanged. for example, removehtmltags("strings are immutable") should return a string equal to "strings are immutable".
