The sort method, when applied to an array of strings, returns a copy of that array in which the strings appear in alphabetical order. For example, if the variable words stored the array ['foo', 'bar', 'biz'], then the call words.sort() would return ['bar', 'biz', 'foo'].

Define a function named BinSearch that implements binary search and store it in arrays.js. Then, create a Web page named bin.html that performs binary searches. Like seq.html, this page should contain a text area in which the user can enter a sequence of words and a text box for specifying the word to search for. When the user clicks a button, the page should sort the words in alphabetical order (using the array method sort) and then call BinSearch to perform the search. As in seq.html, the result of the search (either the index at which the word was found or else -1) should be displayed in a separate text box?
