scala数据结构和算法-05-插入排序实现

package data

import scala.collection.mutable.ListBuffer

object InsertSort {
  def insertSort[T<%Ordered[T]](source:ListBuffer[T]):ListBuffer[T]={
    for(i<-1 until source.length){
      for(j<-(1 to i).reverse){
        val current=source(j);
        val prev=source(j-1);
        if(current<prev){
          source(j-1)=current;
          source(j)=prev;
        }
      }
    }
    source
  }
  def main(args: Array[String]): Unit = {
    val source=ListBuffer(3,5,4,9,1,8,7,6);
    println(insertSort(source).mkString(","))
  }
}
