Huff Challenge #3 (a bit harder... and much more real) Exploit this contract and steal the Ether inside. It's deployed at 0xae7e201257f3f7918e9e8f2f3de998e3d75f7a1d and has 0.1 ETH for you :) Interface: deposit(), withdraw(), and setWithdrawer(address)

Huff challenge #5 🗿🍾⛳️ : We got another fun one for ya Implement the most gas efficient contract that returns true if the calldata represents a signed message from the sender of the tx. If it isn't, do something that makes the transaction run out of gas.
