上上题qSort()函数不支持排序规则函数，形如sorted()函数的key参数，为实现类似目标，横线处分别应填入代码是( )。

def qSort(lst,fx = None):

    if len(lst) <= 1:
        return lst
    else:
        Pivot = lst[0]
        if ________:
            Less = [x for x in lst[1:] if _________]
            Greater = [x for x in lst[1:] if ____________]
            return qSort(Less,fx) + [Pivot] + qSort(Greater,fx)
        else:
            Less = [x for x in lst[1:] if x <= Pivot]
            Greater = [x for x in lst[1:] if x > Pivot]
            return qSort(Less,fx) + [Pivot] + qSort(Greater,fx)

lstA = [1,2,11,12,21,21,2,3,41,4,3]

lstB = qSort(lstA, lambda x:x % 10)
print(lstA, lstB)
