You are searching in integer indexes 0 to #table-1. In lua sequences
go normally from 1 to #table.

And here you are filling them the lua way, from 1

So if you search for the last num you'll never find it.

Anyway, your loop is quite complex, and you've made a major mistake:

If you are a teacher giving an exam, you MAY be able to ask that kind
of questions. If you want help fixing your code you should normally
state what is yur observed problem, otherwise you'll increase the
probability of people deciding 'If he cannot take time to properly
write his questions, I am not taking it to try to answer.'
