The syntax of the set removeFirst() method is:

set.removeFirst()

Here, set is an object of the Set class.

The removeFirst() returns the removed element from the set

Note: Since Sets are unordered collections, the random element is removed and returned.

// removes and returns first element from country
print(country.removeFirst())
