Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

    mapping(address => mapping(address => mapping(uint256 => uint256))) _targetAccessGrants;

    function grantAccess(address userAddress, uint256 documentHash, address targetUserAddress, uint256 permission) public {
        _userAccessGrants[userAddress][documentHash][targetUserAddress] = permission; 
        _targetAccessGrants[targetUserAddress][userAddress][documentHash] = permission;
