冒泡排序应用

if i>j:
    p = i
    i = j
    j = p

11 ##冒泡排序a

20 ##冒泡排序b
21 for n in range(0,len(arr_b)):

23         if n+1<len(arr_b):

29 ##输出第一个数
30 x = 0
31 for num_a in range(0,len(arr_a)):
32     x = int(arr_a[num_a])*(10**(len(arr_a)-num_a-1))+x

34 ##输出第二个数
35 y = 0
36 for num_b in range(0,len(arr_b)):
37     y = int(arr_b[num_b])*(10**(len(arr_b)-num_b-1))+y
