A problem is called "WellKnown" if a similar problem has already been proposed. Dadas, who is proposing problems for the Lemon Cup, wants to avoid proposing WellKnown problems. So he set the following criteria.

• If problem $A$ was proposed before problem $B$ and the algorithms used in problem $A$ include all the algorithms used in problem $B$, then problem $B$ is defined as WellKnown.

There are countless algorithms in the world, but Dadas only knows $K$ algorithms. Therefore, the problems proposed by Dadas only involve these $K$ algorithms.

$N$ problems proposed by Dadas are given in the order they were proposed. For each problem, compare it with previously proposed problems, and print WellKnown if it is WellKnown, and AdHoc otherwise. Note that there may exist problems that do not use any algorithms at all.

The input is given in the following format.

$N \ K$ $S_1$ $S_2$

Print $N$ lines. On the $i$-th line, print whether $i$-th problem is WellKnown or AdHoc.

• $1 \leq N \leq 300\ 000$.
• $1 \leq K \leq 20$.
