How do I solve this exercise below on Arrays using Swift code? 1/4 Exercise - Arrays Assume you are an event coordinator for a community charity event and are keeping a list of who has registered. Create a variable registrationList that will hold strings. It should be empty after initialization. Your friend Sara is the first to register for the event. Add her name to registrationList using the append(_:) method. Print the contents of the collection. Add four additional names into the array using the += operator. All of the names should be added in one step. Print the contents of the collection. Use the insert(_:at:) method to add Charlie into the array as the second element. Print the contents of the collection. Somebody had a conflict and decided to transfer registration to someone else. Use array subscripting to change the sixth element to Rebecca. Print the contents of the collection. Call removeLast() on registrationList. If done correctly, this should remove Rebecca from the collection. Store the result of removeLast() into a new constant deletedItem, then print deletedItem.
