Organised Festival

In order for your festival to be properly managed, you need to define an organizer. The organizer will be the only user to have the right to modify certain properties. By default, you will define the organizer as the contract's deployer.

Instructions

• Create a new Smart contract OrganizedFestival.
• Add a constructor function that takes as parameter a uint to represent the date of the festival and a string to register its place (Like in TimeAndPlace).
• Add functions getStartTime and getPlace that retrieve the starting time and place.
• Add functions updateStartTime and updatePlace that update the corresponding value only if the caller of the function is the organizer (which should be the original deployer of the Smart Contract).

Hint

The constructor function might save the address of the deployer of the contract in an internal variable
