N Snukes called Snuke 1, Snuke 2, ..., Snuke N live in a town.
There are K kinds of snacks sold in this town, called Snack 1, Snack 2, ..., Snack K. The following d_i Snukes have Snack i: Snuke A_{i, 1}, A_{i, 2}, \cdots, A_{i, {d_i}}.
Takahashi will walk around this town and make mischief on the Snukes who have no snacks. How many Snukes will fall victim to Takahashi's mischief?

-----Constraints-----
 - All values in input are integers.
 - 1 \leq N \leq 100
 - 1 \leq K \leq 100
 - 1 \leq d_i \leq N
 - 1 \leq A_{i, 1} < \cdots < A_{i, d_i} \leq N

-----Input-----
Input is given from Standard Input in the following format:
N K
d_1
A_{1, 1} \cdots A_{1, d_1}
\vdots
d_K
A_{K, 1} \cdots A_{K, d_K}

-----Output-----
Print the answer.

-----Sample Input-----
3 2
2
1 3
1
3

-----Sample Output-----
1

 - Snuke 1 has Snack 1.
 - Snuke 2 has no snacks.
 - Snuke 3 has Snack 1 and 2.
Thus, there will be one victim: Snuke 2.
