Is 2nd sample output correct?I think it is wrong.
there n=6,x=3 and k=1.
so the ans will sum of 1,2,4,5,6 which is 18.
in sample output it is 15.
please tell me if I am wrong.

so what actually that line means?
At first move, Jodu will select K consecutive marbles (X, X + 1, X + 2, . . . , X + K ? 1)
starting from X and will remove them
and what about the 1st output?

The problem statement and sample I/O are correct. I can't explain that line any better than it already is written.

n=5,k=2 and x=2.
so the ans will sum of 1,4,5 which is 10.
