salary=float (input( ))

if salary<=5000:

    tax=0

elif salary<=7000:

    tax=(salary-5000)*0.1

elif salary<=10000:

    tax=200+(salary-7000)*0.2

else:

    tax=800+(salary-10000)*0.4

print(salary-tax)

a = [0 for i in range(n+1)] for j in range(n+1)]

a[0][0]=1

for i in range(1,n+1):

    a[i][0]=1

    for j in range(1,i+1)

        a[i][i] = a[i-1][j-1]+a[i-1][j]

x=0

for i in range(1,11,2):

    x+=i

print(x)

from random import randint

x = randint(2,4)*2

a=[9,2,5, 1,3,4,8,7]

n=len(a)

for i in range(0,n- 1):

    k=i

    for j in range(i+1,x):

        if a[k]>a[j]:

            k=j

    if i!=k:

        a[k],a[i]=a[i],a[k]

print(a)

执行后，输出结果不可能是(  )
