若在文本框Text1中输入10242048，则程序执行后，变量x的值为（  ）

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]

表1  某高校学考等级成绩折算表

表2  某学生学考等级成绩单

编写Python程序实现学考成绩总分折算。表2学生的折合分数如图所示。

n= 5

head=0

tail=4

que=['a' , 'b' ,'c' ,'d' ,'e' ]

while head!=tail:

    if head%4==0:

        print (que[head])

    else:

        tail=(tail+1)%n

        que[tail]=que[head]

    head= (head+1)%n

print (que[head])

s="0923 Hangzhou Yayunhui"; t=""

for i in range(len(s)):

    j=s[i]

    if not j>="a" or j>"z":

        t=""

        t=j+t

print(t)

程序运行后，输出的内容是（    ）
