/**
 * Have the function StringChallenge(str) read the str parameter being passed
 *  which will be a string of HTML DOM elements and plain text. The elements
 * that will be used are: b, em, dev, p. For example: if str is
 * “<div><b><p>hello world</p></b></div>” then this string of DOM
 * elements is nested correctly so your program should return true.

If a string is not tested correctly, return the first element encountered
where, if changed into a different element, would result in a properly
formatted string. If the string is not formatted properly, then it will
only be one element that needs to be changed, For example: if str is
“<div><i>hello</>world</b>” then your program should return the string
“div” because if the first <div> element were changed into a <b>, the
string would be properly formatted.

Examples
Input: “<div><div><b></b></div></p>”
Output: “div”

Input: “<div>abc</div><p><em><i>test test test</b></em></p>”
Output: “i”
