Looking at all the arrangements, half of them
have C first and half of them have K first, the
answer would be one half of all the permutations
( possible arrangements )
----------------------------------
Take one-half of this result because the S....S
arrangements are the same after being switched
----------------------------------
So, the answer is:
+%281%2F4%29%2A%28+5%2A4%2A3%2A2%2A1+%29+=+30+
Definitely get a 2nd opinion, too
