Returns a subsequence containing all but the given number of initial elements.
func dropFirst(_ k: Int = 1) -> Self.SubSequence
The number of elements to drop from the beginning of the collection.
kmust be greater than or equal to zero.
A subsequence starting after the specified number of elements.
If the number of elements to drop exceeds the number of elements in the collection, the result is an empty subsequence.
let numbers = [1, 2, 3, 4, 5] print(numbers.dropFirst(2)) // Prints "[3, 4, 5]" print(numbers.dropFirst(10)) // Prints ""
