Problem Description
Ethan has $n$ sets of numbers, each with the following attributes:
- ID: The $i$-th set is numbered $i$.
- Size: The $i$-th set has a size of $num_i$.
- Magic: The $i$-th set has a magic value of $t_i$.
- Numbers: The $i$-th set contains the numbers $c_{i,1}, c_{i,2}, \dots, c_{i,num_i}$.
In Ethan's world, there are only $m+1$ numbers: $0$ to $m$.
Among these $m+1$ numbers, Ethan likes $d$ of them, which are $p_1, p_2, \dots, p_d$, and dislikes the remaining $m-d+1$ numbers.
Ethan wants to delete some sets. Specifically, he will choose an interval $[L, R]$ and delete all sets whose IDs are outside this interval.
- He wants the remaining sets to include all the numbers he likes.
- Among the remaining sets, he wants the count of the numbers he dislikes to be as small as possible (Note: The count refers to the number of occurrences. For example, if $1$ is a disliked number and appears $3$ times in the remaining sets, it counts as $3$ disliked numbers).
- If there are multiple intervals that satisfy the above conditions, he wants the sum of the magic values of the remaining sets to be as large as possible.
Find the interval $[L, R]$ that meets the requirements. If there is no solution, output $-1$. If there are multiple solutions, output any one.
Input Format
The first line contains three integers $n, m, d$.
The second line contains $d$ integers $p_1, p_2, \dots, p_d$.
From the third line to the $(n+2)$-th line: Each line starts with two integers $t_i, num_i$, followed by $num_i$ integers $c_{i,1}, c_{i,2}, \dots, c_{i,num_i}$.
Output Format
One line, if there is no solution, output $-1$. Otherwise, output two integers $L, R$.

Notes
Sample Explanation:
In Sample #1, Ethan can choose the interval $[2, 4]$. This way, the remaining sets contain all the numbers he likes, and only $2$ of the numbers he dislikes appear in these sets.
In Sample #2, there is no valid solution.
Data Range:
This problem uses subtasks.
- Subtask 1: $1 \leq n, m \leq 100$, $20\%$.
- Subtask 2: $1 \leq n, m \leq 500$, $30\%$.
- Subtask 3: $1 \leq n \leq 3000, 1 \leq m \leq 1000, 1 \leq t_i \leq 10^9$, $50\%$.
