def sort(list: List[Int]): List[Int] = list match { case List() => List() case head :: tail => compute(head, sort(tail)) } def compute(data: Int, dataSet: List[Int]): List[Int] = dataSet match { case List() => List(data) case head :: tail => if (data <= head) data :: dataSet else head :: compute(data, tail) } def main(args: Array[String]) { val list = List(3, 12, 43, 23, 7, 1, 2, 0) println(sort(list)) }
2、归并排序
def mergedSort[T](less: (T, T) => Boolean)(list: List[T]): List[T] = { def merged(xList: List[T], yList: List[T]): List[T] = { (xList, yList) match { case (Nil, _) => yList case (_, Nil) => xList case (x :: xTail, y :: yTail) => { if (less(x, y)) x :: merged(xTail, yList) else y :: merged(xList, yTail) } } } val n = list.length / 2 if (n == 0) list else { val (x, y) = list splitAt n merged(mergedSort(less)(x), mergedSort(less)(y)) } } def main(args: Array[String]) { val list = List(3, 12, 43, 23, 7, 1, 2, 0) println(mergedSort((x: Int, y: Int) => x < y)(list)) }
3、快速排序
def quickSort(list: List[Int]): List[Int] = { list match { case Nil => Nil case List() => List() case head :: tail => val (left, right) = tail.partition(_ < head) quickSort(left) ::: head :: quickSort(right) } } def main(args: Array[String]) { val list = List(3, 12, 43, 23, 7, 1, 2, 0) println(quickSort(list)) }
