Bearchild is playing a card game with himself. But first of all, he needs to shuffle the cards. His strategy is very simple: After putting all the cards into a single stack,
he takes out some cards in the middle, from the L-th to the R-th when counting from top to bottom, inclusive, and puts them on the top. He repeats this action again
and again for N times, and then he regards his cards as shuffled.
Given L,R and N, and the initial card stack, can you tell us what will the card stack be like after getting shuffled?
