冒泡、簡單選擇、直接插入、快排（python實現）

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)

 

簡單選擇排序

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
def quicksort(data):
    d=[[],[],[]]
    pivot=data[-1]
    for i in data:
        if i>pivot:
            d[2].append(i)
        elif i<pivot:
            d[0].append(i)
        else:
            d[1].append(i)
    if len(d[0])>1:
        d[0]=quicksort(d[0])
    if len(d[2])>1:
        d[2]=quicksort(d[2])
    d[0].extend(d[1])
    d[0].extend(d[2])
    return d[0]

l=[5,3,7,8,4,1,2,9,10]
l=quicksort(l)
print(l)
