::: Since we are looking for longest sequences, why does A->B->B matter? --[[User:Rdm|Rdm]] 17:32, 25 August 2011 (UTC)
:::: For this task, it doesn't. It's just a matter of general correctness of getting the right length of any sequence. Suppose the task asked for shortest sequences, caching only sorted strings will lead to the conclusion that sequences from A and B are of the same length, while they are not. --[[User:Ledrug|Ledrug]] 17:43, 25 August 2011 (UTC)
