Problem : [Rupsa and the Game](https://www.codechef.com/JAN16/problems/RGAME)↵
Editorial : [link](https://discuss.codechef.com/questions/78208/rgame-editorial)↵
↵
Wrong thing with Editorial :↵
↵
But how many already existing sequence are there? Clearly, 2^(k−1) but when two pairs equal numbers are there then there will not 2^(k-1) sequences because of repetion of sequences, like suppose we have 1, 2, 2, 3, 3 ↵
We can obtain : 1 -> 1 2 -> 1 2 3 -> 2 1 2 3 -> 3 2 1 2 3 ↵
Also, : 1 -> 2 1 -> 3 2 1 -> 3 2 1 2 -> 3 2 1 2 3. So I think the approach is wrong and all have blind folded solved this problem.↵

I have also commented it there, but admin haven't replied yet. Can someone please check what I am saying is correct or not.
