python冒泡排序、希尔排序、快速排序、归并排序、插入排序和堆排序比较

1、快速排序

def  kuaisu(n):
    while len(n)<2:
        return n
    list1=[]
    list2=[]
    middle=n.pop(0)
    for i in n:
        if  middle>i:
            list1.append(i)
        else:
            list2.append(i)
    return  kuaisu(list1)+[middle]+kuaisu(list2)
if __name__ == '__main__':
    import  random
list=[]
for i in  range(9):
    list.append(random.randint(0,60))
print(list)
print(kuaisu(list))

结果：
[5, 12, 55, 25, 30, 43, 29, 16, 1]
[1, 5, 12, 16, 25, 29, 30, 43, 55]

2.1、归并排序1

def merge(a, b):
    c = []
    h = j = 0
    while j < len(a) and h < len(b):
        if a[j] < b[h]:
            c.append(a[j])
            j += 1
        else:
            c.append(b[h])
            h += 1
    if j == len(a):
        for i in b[h:]:
            c.append(i)
    else:
        for i in a[j:]:
            c.append(i)
    #print(c,'!!!!')
    return c
def merge_sort(lists):
    if len(lists) <2:
        #print(lists,'****')
        return lists
    middle = len(lists)//2
    left = merge_sort(lists[:middle])
    right = merge_sort(lists[middle:])
    #print(left,right,'&&&&')
    return merge(left, right)
if __name__ == '__main__':
    import random
lists = []
for i in range(9):
    lists.append(random.randint(0, 60))
print(lists)
print(merge_sort(lists))
