There are $N$ stations on a certain line operated by AtCoder Railway. The $i$\-th station $(1 \leq i \leq N)$ from the starting station is named $S_i$. Local trains stop at all stations, while express trains may not. Specifically, express trains stop at only $M \, (M \leq N)$ stations, and the $j$\-th stop $(1 \leq j \leq M)$ is the station named $T_j$. Here, it is guaranteed that $T_1 = S_1$ and $T_M = S_N$, that is, express trains stop at both starting and terminal stations. For each of the $N$ stations, determine whether express trains stop at that station. ## Input Input is given from Standard Input in the following format: $N$ $M$ $S_1$ $\ldots$ $S_N$ $T_1$ $\ldots$ $T_M$ ## Constrains * $2 \leq M \leq N \leq 10^5$ * $N$ and $M$ are integers. * $S_i$ $(1 \leq i \leq N)$ is a string of length between $1$ and $10$ (inclusive) consisting of lowercase English letters. * $S_i \neq S_j \, (i \neq j)$ * $T_1 = S_1$ and $T_M = S_N$. * $(T_1, \dots, T_M)$ is obtained by removing zero or more strings from $(S_1, \dots, S_N)$ and lining up the remaining strings without changing the order.
