All cinema halls in Berland are rectangles with *K* rows of *K* seats each, and *K* is an odd number. Rows and seats are numbered from 1 to *K*. For safety reasons people, who come to the box office to buy tickets, are not allowed to choose seats themselves. Formerly the choice was made by a cashier, but now this is the responsibility of a special seating program. It was found out that the large majority of Berland's inhabitants go to the cinema in order to watch a movie, that's why they want to sit as close to the hall center as possible. Moreover, a company of *M* people, who come to watch a movie, want necessarily to occupy *M* successive seats in one row. Let's formulate the algorithm, according to which the program chooses seats and sells tickets. As the request for *M* seats comes, the program should determine the row number *x* and the segment [*y*_{l}, *y*_{r}] of the seats numbers in this row, where *y*_{r} - *y*_{l} + 1 = *M*. From all such possible variants as a final result the program should choose the one with the minimum function value of total seats remoteness from the center. Say, — the row and the seat numbers of the most "central" seat. Then the function value of seats remoteness from the hall center is . If the amount of minimum function values is more than one, the program should choose the one that is closer to the screen (i.e. the row number *x* is lower). If the variants are still multiple, it should choose the one with the minimum *y*_{l}. If you did not get yet, your task is to simulate the work of this program.

The first line contains two integers *N* and *K* (1 ≤ *N* ≤ 1000, 1 ≤ *K* ≤ 99) — the amount of requests and the hall size respectively. The second line contains *N* space-separated integers *M*_{i} from the range [1, *K*] — requests to the program.
