# removeLast(_:)

Removes the specified number of elements from the end of the
collection.

```
mutating func removeLast(_ k: Int)
```

## Parameters

`k`

The number of elements to remove from the collection.
`k` must be greater than or equal to zero and must not exceed the
number of elements in the collection.

## Discussion

Attempting to remove more elements than exist in the collection
triggers a runtime error.

Calling this method may invalidate all saved indices of this
collection. Do not rely on a previously stored index value after
altering a collection with any operation that can change its length.

> Complexity: O(*k*), where *k* is the specified number of elements.
