// fee is zero, is to compute the price of the assets locked in its liquidity
// pool, and divide it by the total amount of LP tokens issued:
//
// (p_0 * r_0 + p_1 * r_1) / LP_supply (1)
//
// where r_0 and r_1 are the reserves of the two tokens held by the pool, and
// p_0 and p_1 are their respective prices in some reference unit of account.
//
// However, the price of LP tokens (i.e. pool shares) needs to be evaluated
// based on reserve values r_0 and r_1 that cannot be arbitraged, i.e. values
// that give the two halves of the pool equal economic value:
//
// r_0 * p_0 = r_1 * p_1 (2)
//
// Furthermore, two-asset constant product pools, neglecting fees, satisfy
// (before and after trades):
//
// r_0 * r_1 = k (3)
//
// Using (2) and (3) we can compute R_i, the arbitrage-free reserve values, in a
// manner that depends only on k (which can be derived from the current reserve
// balances, even if they are far from equilibrium) and market prices p_i
// obtained from a trusted source:
//
// R_0 = sqrt(k * p_1 / p_0) (4)
// and
// R_1 = sqrt(k * p_0 / p_1) (5)
//
// The value of an LP token is then, replacing (4) and (5) in (1):
//
// (p_0 * R_0 + p_1 * R_1) / LP_supply
// = 2 * sqrt(k * p_0 * p_1) / LP_supply (6)
//
// k can be re-expressed in terms of the current pool reserves r_0 and r_1:
//
// 2 * sqrt((r_0 * p_0) * (r_1 * p_1)) / LP_supply (7)
//
// The structure of (7) is well-suited for use in fixed-point EVM calculations, as the
// terms (r_0 * p_0) and (r_1 * p_1), being the values of the reserves in the reference unit,
// should have reasonably-bounded sizes. This reduces the likelihood of overflow due to
// tokens with very low prices but large total supplies.

* This implementation is agnostic to the way tokens are created. This means

*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin guidelines: functions revert instead
* of returning `false` on failure. This behavior is nonetheless conventional
* and does not conflict with the expectations of ERC20 applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

/**
*
*
*
*
* ATTENTION!
*
* This code? IS NOT DESIGNED FOR ACTUAL USE.
*
* The author of this code really wishes you wouldn't send your ETH to it, but it's been
* done with P3D and there are very happy users because of it.
*
* No, seriously. It's probablly illegal anyway. So don't do it.
*
* Let me repeat that: Don't actually send money to this contract. You are
* likely breaking several local and national laws in doing so.
*
* This code is intended to educate. Nothing else. If you use it, expect S.W.A.T
* teams at your door. I wrote this code because I wanted to experiment
* with smart contracts, and I think code should be open source. So consider
* it public domain, No Rights Reserved. Participating in pyramid schemes
* is genuinely illegal so just don't even think about going beyond
* reading the code and understanding how it works.
*
* Seriously. I'm not kidding. It's probablly broken in some critical way anyway
* and will suck all your money out your wallet, install a virus on your computer
* sleep with your wife, kidnap your children and sell them into slavery,
* make you forget to file your taxes, and give you cancer.
*
*
* What it does:
*
* It takes 50% of the ETH in it and buys tokens.
* It takes 50% of the ETH in it and pays back depositors.
* Depositors get in line and are paid out in order of deposit, plus the deposit
* percent.
* The tokens collect dividends, which in turn pay into the payout pool
* to be split 50/50.
*
* If you're seeing this contract in it's initial configuration, it should be
* set to 200% (double deposits), and pointed at PoWH:
* 0xB3775fB83F7D12A36E0475aBdD1FCA35c091efBe
*
* But you should verify this for yourself.
*

/*
Geass is a supernatural ability which certain people can bestow upon others. This power is usually called the Power of Kings. According to an English edition of "Newtype", the power of Geass has something to do with the very existence of humankind, and it may be used to destroy, control, or transform just about anything.
The power of Geass increases with use, and should the user lack the willpower, they may be consumed by it.
Lelouch states that the Geass is a form of wish. However, people who have Geass are not immune to the Geass effects of others. The Geass is represented by a glowing, bird-shaped symbol.

// Invest Ethereum into a long term stable solution where
// your investment can grow organically as the system expands.
// You will gain +1.5% of your invested Ethereum every day that
// you leave it in the Ether Piggy Bank!
// You can withdraw your investments at any time but it will
// incur a 20% withdrawal fee (~13 days of investing).
// You can also invest your profits back into your account and
// your gains will compound the more you do this!
//
// Big players can compete for the investment positions available,
// every time someone makes a deposit into the Ether Piggy Bank,
// they will receive a percentage of that sale in their
// affiliate commision.
// You can buy this position off anyone and double it's current
// buying price but every 3-7 days (depending on the position),
// the buying price will halve until it reaches 0.125 ether.
// Upon buying, the previous investor gets 75% of the buying price,
// the dev gets 5% and the rest goes into the contract to encourage
// an all round balanced ecosystem!
//
// You will also receive a 5% bonus, which will appear in your
// affiliate commission, by referring another player to the game
// via your referral URL! It's a HYIP on a smart contract, fully
// transparent and you'll never need to worry about an exit scam or
// someone taking all the money and leaving!

* @dev Contract module that allows children to implement role-based access
* control mechanisms. This is a lightweight version that doesn't allow enumerating role
* members except through off-chain means by accessing the contract event logs. Some
* applications may benefit from on-chain enumerability, for those cases see
* {AccessControlEnumerable}.
*
* Roles are referred to by their `bytes32` identifier. These should be exposed
* in the external API and be unique. The best way to achieve this is by
* using `public constant` hash digests:
*
* ```
* bytes32 public constant MY_ROLE = keccak256("MY_ROLE");

*
* Roles can be used to represent a set of permissions. To restrict access to a
* function call, use {hasRole}:
*
* ```
* function foo() public {
* require(hasRole(MY_ROLE, msg.sender));
* ...
* }
* ```
*
* Roles can be granted and revoked dynamically via the {grantRole} and
* {revokeRole} functions. Each role has an associated admin role, and only
* accounts that have a role's admin role can call {grantRole} and {revokeRole}.
*
* By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
* that only accounts with this role will be able to grant or revoke other
* roles. More complex role relationships can be created by using
* {_setRoleAdmin}.
*
* WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
* grant and revoke this role. Extra precautions should be taken to secure
* accounts that have been granted it.

/**
* @dev Wrappers over Solidity's arithmetic operations with added overflow
* checks.
*
* Arithmetic operations in Solidity wrap on overflow. This can easily result
* in bugs, because programmers usually assume that an overflow raises an
* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.
*
* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.

MiniZombie
https://t.me/minizombieinu
The appearance of a group of Minizombie is the worst case scenario of what is already a worst case scenario. Everytime MiniZombie appears, they appear as a chainswarm. There is no precise number of zombies that comprises a chainswarm. One cannot tell where the boundary of the group ends - it stretches past the horizon, or the immediate field of view.
Without a well prepared platoon of organized veteran fighters. There simply is no way for survivors to defeat this MiniZombie army. With the enormous number of MiniZombie, there is no guarantee you're not surrounded, thus your only option is to JOIN the Minizombie army!
MiniZombie token is dedicated to present you a deflationary experience! This token is designed with a deflationary mechanism, 5% of our token will be automatically burned to ensure the stability and prospect of the token. We believe that this token will grow exponentially like how zombies grow rapidly.
MiniZombie is going to be the deadliest and viral token you have ever seen!

* チョコボ 🐥🐥🐥
* Chocobo, also called Chocob, is a recurring animal in the series of Final Fantasy. Large avian creatures, chocobos roughly act as the equivalent of horses, being domesticated for use as mounts, for pulling carts and carriages and for racing. Chocobos are known to be intelligent and to understand human language.
* Chocobos can usually be found in chocobo forests situated throughout the world. They come in several varieties. The regular chocobos can be used to travel around the world, but they flee when dismounted. In several series, a chocobo eats a chili pepper, it runs wildly due to the burning of the tongue.
* Chocobo Inu is the “proof of stake token” for CAW and SQUAWK. When you stake your Chocobo Inu token into the DAO, you are given CAW and SQUAWK. This can be swapped back at any time into the amount of Chocobo Inu you staked originally, plus any rewards that were given to the DAO in the time period you owned Chocobo Inu.
