Plz who can clarify what 'parsing 'is to me and what does it mean to parse a valid non-negative integer

Question

I really don't get it even with my research

Answer 1

I think it may help if you included the full sentence or paragraph where the "parsing" word is used in the original question Description.

My understanding of parsing is to extract and group (classify) usable or meaningful information from raw data; that contains for example - data and metadata.

Answer 2

Thanks I understand stand now

Answer 3

My understanding can be wrong, I advise you to write the full sentence containing "parsing" word in your Description (above) to have more people to drop their opinions in.
