Generic Instance Method

# lexicographicallyPrecedes(_:)

Returns a Boolean value indicating whether the sequence precedes another sequence in a lexicographical (dictionary) ordering, using the less-than operator (`<`) to compare elements.

## Declaration

Available when Element conforms to Comparable.

## Parameters

`other`

A sequence to compare to this sequence.

## Return Value

`true` if this sequence precedes `other` in a dictionary ordering; otherwise, `false`.

## Discussion

This example uses the `lexicographicallyPrecedes` method to test which array of integers comes first in a lexicographical ordering.

Complexity: O(m), where m is the lesser of the length of the sequence and the length of `other`.

### Comparing Arrays

`static func == (Array<Element>, Array<Element>) -> Bool`

Returns a Boolean value indicating whether two arrays contain the same elements in the same order.

`static func != (Array<Element>, Array<Element>) -> Bool`

Returns a Boolean value indicating whether two values are not equal.

`func elementsEqual<OtherSequence>(OtherSequence) -> Bool`

Returns a Boolean value indicating whether this sequence and another sequence contain the same elements in the same order.

`func elementsEqual<OtherSequence>(OtherSequence, by: (Element, OtherSequence.Element) -> Bool) -> Bool`

Returns a Boolean value indicating whether this sequence and another sequence contain equivalent elements in the same order, using the given predicate as the equivalence test.

`func starts<PossiblePrefix>(with: PossiblePrefix) -> Bool`

Returns a Boolean value indicating whether the initial elements of the sequence are the same as the elements in another sequence.

`func starts<PossiblePrefix>(with: PossiblePrefix, by: (Element, PossiblePrefix.Element) -> Bool) -> Bool`

Returns a Boolean value indicating whether the initial elements of the sequence are equivalent to the elements in another sequence, using the given predicate as the equivalence test.

`func lexicographicallyPrecedes<OtherSequence>(OtherSequence, by: (Element, Element) -> Bool) -> Bool`

Returns a Boolean value indicating whether the sequence precedes another sequence in a lexicographical (dictionary) ordering, using the given predicate to compare elements.
