实例方法
suffix(_:)
返回一个子序列,最长为给定的最大长度,包含序列的最终元素。
声明
func suffix(_ maxLength: Int) -> [Self.Element]
参数
maxLength
要返回的最大元素数。
maxLength
的值必须大于或等于零。
详述
序列必须是有限的。如果最大长度超过序列中元素的数量,则结果包含序列中的所有元素。
let numbers = [1, 2, 3, 4, 5]
print(numbers.suffix(2))
// Prints "[4, 5]"
print(numbers.suffix(10))
// Prints "[1, 2, 3, 4, 5]"
