true this is a good case of bad pratices the code should be/try to be easy to read to any person new to the code

Pleasure to my eyes

Difficult to read

give us a hint

test 3 is '369'
According to task, 1 number can be either one of '326'
2 - '6359'
3 - '968'
So your choices aren't possible. Probably you're forgetting about sequence which is important

lol
