swift閉包練習（第五章）

swift 的閉包

```swift
func mysort(array:inoutArray<Any>,sortClus:(Int,Int)->Bool) -> Array<Any>{
    //    冒泡排序
    for indexI in array.indices {
        if indexI == array.count -1{
            break
        }
        for indexJ in 0...((array.count-1) - indexI -1) {
            if sortClus(indexJ,indexJ+1) {
                
            }
            else{
                //元素交換
                swap(&array[indexJ], &array[indexJ+1])
                array.swapAt(indexJ, indexJ+1)
            }
        }
    }
    
    return array
}
var array:Array<Any> = [1,2,9,3,6,5,4]

mysort(array: &array,sortClus: { (index:Int, nextIndex:Int) ->Bool in
    return (array[index]as! Int) > (array[nextIndex]as! Int)
})
print(array)
