	/* Define variable owner of the type address */
	address owner;

	/* This function is executed at initialisation and sets the owner of the contract */
	constructor() public { owner = msg.sender; }

	/* Function to recover the funds of the contract */
	function kill() public { if (msg.sender == owner) selfdestruct(msg.sender); }
}

contract greeter is mortal {
	/* Define variable greeting of the type string */
	string greeting;

	/* This runs when the contract is executed */
	constructor(string memory _greeting) public {
		greeting = _greeting;
	}

	/* Main Function */
	function greet() public view returns (string memory) {
