實例方法
elements
elementsEqual(_:)
返回一個布爾值,指示此序列和另一個序列是否包含相同順序的相同元素。
聲明
func elementsEqual<OtherSequence>(_ other: OtherSequence) -> Bool where OtherSequence : Sequence, Self.Element == OtherSequence.Element
當
Element
符合 Equatable
時可用。返回值
true
如果此序列和 other
包含以相同順序的相同元素。
參數
other
要與此序列進行比較的序列。
詳述
至少有一個序列必須是有限的。
此示例測試一個可數範圍是否與另一個可數範圍和數組共享相同的元素。
let a = 1...3
let b = 1...10
print(a.elementsEqual(b))
// Prints "false"
print(a.elementsEqual([1, 2, 3]))
// Prints "true"
