# dropLast(_:)

Returns a sequence containing all but the given number of final elements.

## Declaration

```swift
func dropLast(_ k: Int = 1) -> [Self.Element]
```

## Return Value

Return Value A sequence leaving off the specified number of elements.

## Discussion

Discussion The sequence must be finite. If the number of elements to drop exceeds the number of elements in the sequence, the result is an empty sequence. let numbers = [1, 2, 3, 4, 5] print(numbers.dropLast(2)) // Prints "[1, 2, 3]" print(numbers.dropLast(10)) // Prints "[]" note: O(n), where n is the length of the sequence.
