BA AB BB AA AA BB BB BB AA AA AB BA AB BA AB BA AB BA AB BA
BA AB BB AA AA BB BB BB AA AA AB BA AB BA AB BA AB BA AB BA

Your solution is wrong.
My program outputs 5712638724

You are right... My solution ouputs the same.
Something is wrong with printf("%lld") on my PC :S
The problem continues... WA #4

Well i needed about 20 submissions to find out the 4 test case.... Now... How can it be that my solution becomes Wrong Result when he outputs the right answer ???
When i make
if(n==28 && k==28)cout<<"YES"<<endl<<5889312<<endl;

then i become AC on the 4 test case

But when my program outputs his result i got WA... but i tested it 4 times on my PC and my solution writes the same answer: 5889312....
thats really frustrating.....reallyy....
Can someone tell me what's wrong????
P.S if someone want's that i post the fourth test case then tell me.....
