We have a grid with $n$ rows and $7$ columns. We call it a calendar. The cell at $i$\-th row and $j$\-th column is denoted $(i, j)$. ![image](https://atcoder.jp/img/s8pc-4/1bef402eeaddb846eb2ea4d386a1ed3d.png) Initially, each cell at $(i, j)$ contains the integer $7i + j - 8$, and each cell is white. Snuke likes painting, so he decided integer $m$, and did $q$ operations with a calendar. ・In $i$\-th operation, he paint black on the cell in which an integer is written such remainder of dividing by $m$ is $a_i$. Please count the number of connected white parts. Note that if two adjacent cells are white, the cells belong to the same connected part. ## Input Format The input format is following: $n$ $m$ $q$ $a_1$ $a_2$ ... $a_q$ [samples]
