swift3.0选择排序法

//选择排序-升序
func minMax(array: inout [Int]) {

    for i in (0..<array.count){
        var k = i
        for j in (k+1..<array.count){
            if(array[k] > array[j]){
                k = j
            }
        }
        if(k != i){
            let temp = array[k]
            array[k] = array[i]
            array[i] = temp
        }
    }

    print(array)
}

var array = [8,-6,2,109,3,71]
minMax(array: &array)
