  1. Detect buffer underflow in get_th() 

    If get_th() can receive input that is not a number,
then it can also receive empty input.

Empty input with zero length can result in a buffer underflow
when accessing *(num + (len - 1)), as (len - 1) would produce a negative index.
Add a check for zero-length input to prevent it.
