This has not been tested very well\n// nor optimized - cut me some slack. This is heavily inspired from the project \"I Am The Chad\".\n//\n// Goal: Create a smart contract (a \"player\") by implementing the IPlayer interface that uses the smallest\n// size of bytecode and uses the smallest amount of gas to solve the problem.\n//\n// Problem: An array of length 10 will be pseudo randomly generated along with a target number `n`. Find the\n// 3 indexes in the array where the values of the array at the 3 indexes sum up to `n`.\n//\n// e.g. inputArr = [1,2,3,4,5,6,7,8,11,15], n = 18.\n// solution is [1,4,8] becaues inputArr[1] + inputArr[4] + inputArr[8] == 18.\n//\n// Constraints: The input array will always be length 10. All numbers in the inputArr are [0, 49]. ANY permutation\n// of 3 indexes are allowed as long as they are all unique indexes and sum up to `n`. There will ALWAYS be a set of 3\n// numbers that add up to `n`.\n//\n// Everytime you write a more optimized player contract, you get minted THE OPTIMIZOR NFT and the previous optimizor's\n// NFT is burnt. There will always just be 1 holder - the current best optimizor.\n//\n// You get to mint the NFT by having the LOWEST score. score = bytecode_size + gasUsed().\n//\n// How to play:\n// 1. Create a player contract by implementing IPLAYER.sol\n// It is CRUCIAL to set the owner of the player contract to be the EOA you will be calling IAmTheOptimizor.sol from. We check to see\n// msg.sender == player.owner() to prevent random ppl from using your code and cheating.\n//\n// 2. Implement solve(). The first argument is the inputArr and second arg is the target number. Return an array of length 3\n// of the 3 indexes.\n//\n// 3. Once you finished your player contract, deploy your contract and call becomeTheOptimizor(player_contract_address) when you think\n// you can beat the current best optimizor. NOTE: The txn WILL fail if your player is less optimized than the current optimizors\n// that holds the NFT.\n//\n// Have fun!\n/// @author: 0xBeans\n\npragma solidity ^0.8.13;\n\nimport \"./IPlayer.sol\";\nimport \"openzeppelin/token/ERC721/ERC721.sol\";\nimport \"openzeppelin/access/Ownable.sol\";\n\nimport {console} from \"forge-std/console.sol\";\n\ncontract IAmTheOptimizor is ERC721, Ownable {\n // used to generate random numbers in array\n uint256 public constant BIT_MASK_LENGTH = 10;\n uint256 public constant BIT_MASK = 2**BIT_MASK_LENGTH - 1;\n\n struct LowestPoints {\n address optimizor;\n uint64 bytecodeSize;\n uint64 gasUsage;\n uint64 totalScore;\n }\n\n // current best optimizor\n LowestPoints public lowestPoints;\n\n // history of optimizors\n address[] public hallOfFame;\n\n string internal _baseTokenUri;\n\n constructor() ERC721(\"I Am The Optimizor\", \"IAMTHEOPTIMIZOR\") {\n // set to highest limits so first submission is new optimizor\n lowestPoints = LowestPoints(\n address(0),\n type(uint64).max,\n type(uint64).max,\n type(uint64).max\n );\n\n _mint(msg.sender, 1);\n hallOfFame.push(msg.sender);\n }\n\n function becomeTheOptimizor(address player) external {\n // check so players dont use other ppls code\n require(IPlayer(player).owner() == msg.sender, \"not your player\");\n\n // grab bytecode size\n uint256 size;\n assembly {\n size := extcodesize(player)\n }\n\n unchecked {\n // pseudo random number to seed the arrays\n uint256 seed = uint256(\n keccak256(\n abi.encodePacked(\n block.coinbase,\n block.number,\n block.timestamp,\n size\n )\n )\n );\n\n // generate random arrays using seed\n uint256[10] memory inputArr = constructProblemArray(seed);\n\n // we shift the seed by 100 bits because we used the first 100 bits\n // to see the inputArr.
