getTokenIdOfAnEventManager

This view function retrieves the token ID associated with the event manager of a specific event. It takes one parameter:

• _eventId: The unique identifier for the event.

```remix-solidity
/**
    GetTokenIdOfAnEventManager: Get the token ID associated with the event manager of a specific event.
    @param _eventId: The unique identifier for the event.
    @return tokenId: The token ID of the event manager.
    */
    function getTokenIdOfAnEventManager(string calldata _eventId)
        public
        view
        returns (uint256)
    {
        // Return the token ID of the event manager for the specified event
        return s_eventIdToTokenIds[_eventId][0];
    }
```

Explanation:

The function retrieves the token ID of the event manager from the mapping s_eventIdToTokenIds using the provided event ID. It then returns the token ID associated with the event manager.

It's important to note that this function assumes that the event manager's token ID is stored at index 0 in the array associated with the provided event ID in the s_eventIdToTokenIds mapping. This implies that each event has only one event manager, and their token ID is stored at the first position in the array. If the assumption does not hold, the behavior of this function may not be as expected.
