Rules
You can pick between separating stanzas with whitespace or newlines, so either:
ABA BCB...
OR
ABA
BCB
...
A single trailing whitespace allowed per line and one trailing newline allowed.
Output can be either uppercase or lowercase.
This is code-golf, so the shortest code in bytes for each language wins.
