IF N=K?

What should I do,when n=k.For example n=k=3

Possible ways

LBL

BLB

BBB

BBL

LBB

LLB

AND

LLL.

Should I count LLL too?

Problem says:

заменить некоторые «лимоны» на гораздо более политкорректные «бананы» таким образом, чтобы задача всё-таки была допущена к контесту. Сколькими способами это можно сделать?

I think I shouldn't count LLL too.Am I right?

Thank!

Re: IF N=K?

Read the problem statement carefully:

"if a word "lemon" occurs more than K times successively, the problem will be immediately disqualified from the contest"

Why don't you count case LLL and (what is more strange) case BLL??? They both satisfy problem statement requirement. Right answer for test 3 3 is 8.
