Detecting Delegate Calls

Download quests in Questplay

Mindeaters exert control over their prey using delegate calls. For a contract to defend itself from a mindeater, it needs to distinguish delegate calls from regular function calls.

The Mind contract needs to implement the following function:

Function	Description
`isDelegateCall() -> bool`	Returns true if the current call is from a delegate call, returns false otherwise.

Your Task

In contracts/Mind.sol implement isDelegateCall().

You can modify the constructor body and add any state variables that you might need.
