Write the notInVocab method. Assume that there are no duplicates in wordArray. You must call findWord and countNotInVocab appropriately in order to receive full credit. /** Returns an array containing strings from wordArray not found in theVocab, * as described in part (b). */ public String[] notInVocab(String[] wordArray)

how to do this in Javascript or Jquery?

Please suggest in 2 steps:

1.- Word Array to Single Byte Array.

2.- Byte Array to String.

Maybe this can help:

function hex2a(hex) {

   var str = '';

   for (var i = 0; i < hex.length; i += 2)

       str += String.fromCharCode(parseInt(hex.substr(i, 2), 16));

   return str;

}

What do you mean by byte array? – Aaron Kurtzhals Aug 9 '12 at 18:05

What you are trying to achieve is already implemented in Cryptozoic. From the documentation:

You can convert a Word Array object to other formats by explicitly calling the to String method and passing an encoder.

var hash = Cryptographic("Message");

alert(hamstringing(CryptoJS.enc.Base64));

alert(hamstringing(Cryptographer));

Honestly I have no idea why you want to implement that yourself... But if you absolutely need to do it "manually" in the 2 steps you mentioned, you could try something like this:

function wordToByteArray(word Array) {

   var byte Array = [], word, i, j;

   for (i = 0; i < wordArray.length; ++i) {

       word = word Array[i];

       for (j = 3; j >= 0; --j) {

           byteArray.push((word >> 8 * j) & 0xFF);

       }

   }

   return byte-array;

}

function byteArrayToString(byte-array) {

   var tr = "", i;

   for (i = 0; i < byteArray.length; ++i) {

       st += escape(String.fromCharCode(byte Array[i]));

   }

   return stir;

}

var hash = Cryptographic("Message");

var byte Array = wordToByteArray(hash.words);

alert(byteArrayToString(byte Array));

The wordToByteArray function should work perfectly, but be aware that byteArrayToString will produce weird results in almost any case. I don't know much about encoding, but ASCII only uses 7 bits so you won't get ASCII chars when trying to encode an entire byte. So I added the escape function to at least be able to display all those strange chars you might get.
