Implementation
String decryptWordHex(int factor, String encryptedWord) {
List<String> decryptedChars = [];
List<String> charList = encryptedWord.split('|');
for (var i = 0; i < charList.length; i++) {
String result = decryptLetterHex(factor, charList[i]);
decryptedChars.add(result);
}
String newlyDecryptedString = decryptedChars.join('');
return newlyDecryptedString;
}
