冒泡排序
l=[3,5,7,8,4,1,2,9,10]
length=len(l)
for i in range(length):
for j in range(length-i-1):
if l[j]>l[j+1]:
temp=l[j]
l[j]=l[j+1]
l[j+1]=temp
print(l)?
简单选择排序
l=[3,5,7,8,4,1,2,9,10]
length=len(l)
for i in range(length):
m=l[i]
tag=i
for j in range(i,length):
if m>l[j]:
m=l[j]
tag=j
l[tag]=l[i]
l[i]=m
print(l)直接插入排序
l=[5,3,7,8,4,1,2,9,10]
length=len(l)
for i in range(1,length):
for j in range(i-1,-1,-1):
if l[j+1]<l[j]:
temp=l[j+1]
l[j+1]=l[j]
l[j]=temp
else:break
print(l)快速排序

d[2].append(i)
elif i<pivot:
