# elementsEqual(_:) Returns a Boolean value indicating whether this sequence and another sequence contain the same elements in the same order. ``` func elementsEqual(_ other: OtherSequence) -> Bool where OtherSequence : Sequence, Self.Element == OtherSequence.Element ``` ## Parameters `other` A sequence to compare to this sequence. ## Return Value `true` if this sequence and `other` contain the same elements in the same order. ## Discussion At least one of the sequences must be finite. This example tests whether one countable range shares the same elements as another countable range and an array. ``` let a = 1...3 let b = 1...10 print(a.elementsEqual(b)) // Prints "false" print(a.elementsEqual([1, 2, 3])) // Prints "true" ``` > Complexity: O(*m*), where *m* is the lesser of the length of the > sequence and the length of `other`. --- Copyright © 2026 Apple Inc.
