Do you understand what the i += 1 does ? It is the same as i++,
am I right ?
The difference lies in the timing of when the increment takes place
(immediately in the case of i += 1, and after the value is used in
the case of i++). Do you think the distinction mentioned makes a
difference for the algorithm ?
