The above code seems to be OK for "row" >= 2. What happens when there
are two or more rows?

Some style comments: "row" is a confusing name; I'd call it "nrows" or
something like that. "val" would be better as "column_index" or
"colx", "ss" as "row_index" or "rowx". Your while loop is better
expressed as a for loop.
