qSort()函数需要实现类似sorted()函数的key参数的排序规则功能，补全下列代码中横线处的内容，正确的是（）。

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)
