Sorry for not replying earlier, but I've just had my
appendix removed and I only got back from the hospital
yesterday.
What you could do it is have an array (or two, if you
want) and check the artist's name (after the inital
sort) and make a note of the range that that
particular artist comes at in the array. E.g.
Array position Array contents
============== ===============
1 Blur
2 Chemical Bros
3 Chemical Bros
4 Duran Duran
So you would have a start position of 2 and an end
position of 3. Next you would do your bubble sort for
the song title array, but only in the range of 2 to 3
instead of everything in the array.
I hope that helps
Kind regards,
Francis.
