Wrong output-something missing in algorithm about courses-project HOT 4 CLOSED

Hi @mr-robot77, can you also specific which algorithm is giving wrong output along with

• inputs
• expected output
• incorrect output.

from courses-project.

in the python ch2 string folder
returner program has an issue in runtime output
this program is about a safe with k rotating locks with a sequence of numbers from 1 to 9 and our mission is finding to k-digit code from input and in the output should give the minimum number of rotation of the wheels for the number to be equal to the code.
if we get this input:
3 123 241356789 987546231 956874231
our expected output should be this:
7
but because of something is missing in define of algorithm of this problem, so we get this wrong output:
2148921431256

Hey,

1. I not able to understand what you are trying to achieve
2. The code implies that locks is a list of sub lists but the input provided is unclear about how many elements goes in each iteration
   Eg.

k = 3
code = 123

for k = 1
input can be 241356789
OR
input can be 241356789 987546231
OR
input can be 241356789 987546231 956874231

Therefore, please provide an input separated by new line

3. if number in locks[i]: will always result in False since it's checking if 1 is an element in a sub list and this is never the case
   Therefore, my answer in always 0

i solved the issues and change the code
now it's worked correctly
