    "Notes:\n",
    "\n",
    "* `KEY` can be positive or negative number of any reasonable size (-1000 ... 1000)\n",
    "* correct solution for default given values is `epaopuafbuabmmanzapsbohft`\n",
    "* keep in mind that you (or user) have to provide custiom crypting TABLE, do not use all characters or something like that\n",
    "* once again: your file MUST start with constants: `MESSAGE`, `TABLE`, `KEY`. Do not rename them! Do not ask for user input! Just process these variables and print output\n",
    "\n",
    "FAQ:\n",
    "\n",
    "* **What about spaces?** - spaces should be handled as any other character - if the space character is in `TABLE`, it can be in `MESSAGE` also\n",
    "* **What about capital letters?** - the same rule applies for capital letter, if user provide `TABLE` with capital letters, it is possible to use them also in `MESSAGE`\n",
