VBA Delete Rows In Between Cell Values

Within one column, there are cells with values A, B, and C for example. I want a loop that
- delete all rows from the first row to the row where A occurs,
- delete all rows BETWEEN where B and A occurs.
- and then finally, delete the single rows where C occurs.

This might seem I'm just deleting everything but obviously there are more "A" and "B"s in the column.

1
2
3 A
4
5 B
6
7 A
8 B
9 C
10

So in this example, rows 1 to 3 are deleted since I want to delete row 1 to the row where A is; rows 5 to 7 are gone (B to A); then finally row 8 is gone since C is there. Whether it's A/B inclusive doesn't matter..I just would like to see the (simple) logic.
