1 is greater than 0. So we call recursion(0). Nothing printed yet. 0 is not greater than 0, so we return 0. We don't print anything here; So for recursion recursion(1) we got 1 + 0 (from previous line) so we print 1 and return 1; For recursion(2) we got 2 + 1 (from previous line) so we print and return 3; For recursion(3) we got 3 + 3 so we ...
