What ever I did I can't and you also will find it hard

Question

cd=input()
list=[]
for i in cd:
list.append(int(i))

for i in range(1,len(list)):
if i % 2!= 0:
list[i] *= 2
list.reverse()

def sub9(list):
for i in range(len(list)):
if list[i]>9:
list[i]-9
return list
print(sub9(list))

1 reverse all nums (must be 16) you will take a string as an input make it list
2 multiple every even position by 2
3 subtract 9 from every number greater than 9
4 then the sum of numbers must be modulo 10 like 70 %10 ==0
5 all true true else false

Iam stuck at step 3

Answer 1

ZIZO Abd alkawy ,

After reading the problem statement I lil modified this code...now it passed all test cases ...
as you missed to mention about that length should be 16...that only not added in the code... that's why it doesn't work...

now check this....
