Problem 3644: roboti

Task

Sara loves robotics and in the project she is currently running, she built $n$ robots for which she knows their abilities, expressed in a certain unit of measure. However, $K$ of them, given by their indices have some vulnerabilties and they may break down, so Sara is now asking you if we take randomly one of the robots with the highest ability, there is a chance of having a vulnerability when testing.

If this happens, print Da (Yes in Romanian), otherwise print Nu (No in Romanian).

Input data

The first line contains two integers, $n$ and $k$ .

The second line contains the abilities of the $n$ robots.

The third line contains the indices of the robots which have vulnerabilities.

Output data

Pe prima linie se va găsi only one message, Da or Nu.

Constraints and clarifications

$1 \leq K \leq N \leq 100$
$1 \leq A_i \leq 100$
$1 \leq B_i \leq N$ , $B_i \neq B_j, \forall 1 \leq i < j \leq N$

Example 1

stdin

5 3
6 8 10 7 10
2 3 4

stdout

Da

Explanation

The greatest ability of a robot is $10$ . The robots $2, 3, 4$ are vulnerable. Among them, robot $3$ has an ability equal to $10$ , so there is a possibility that we have a vulnerability when testing one of the robots with maximum ability.
