Problem Statement

You are given $N$ strings $S_1,S_2,\ldots, S_N$. Let $M = \displaystyle\sum_{i=1}^N \frac{|S_i|(|S_i|+1)}{2}$. For a string $S$ and integers $L$ and $R$, let us denote by $S[L, R]$ the substring consisting of the $L$-th through $R$-th characters of $S$.

A sequence of triples of integers $((K_1, L_1, R_1), (K_2, L_2, R_2), \ldots, (K_M, L_M, R_M))$ of length $M$ satisfies the following conditions:

• The $M$ elements are pairwise distinct.
• For all $1 \leq i \leq M$, it holds that $1 \leq K_i \leq N$ and $1 \leq L_i \leq R_i \leq |S_{K_i}|$.
• For all $1 \leq i \leq j \leq M$, it holds that $S_{K_i}[L_i, R_i] \leq S_{K_j}[L_j, R_j]$ in the lexicographical order.

You are given $Q$ integers $x_1,x_2,\ldots, x_Q$ between $1$ and $M$, inclusive. For each $1 \leq i \leq Q$, find a possible instance of $(K_{x_i}, L_{x_i}, R_{x_i})$. We can prove that there always exists a sequence of triples that satisfies the conditions. If multiple triples satisfy the conditions, print any of them. In addition, among different $x_i$'s, the conforming sequence of triples does not have to be common.

Constraints

• $1 \leq N \leq 10^5$
• $1 \leq \lvert S_i\rvert \leq 10^5$
• $\displaystyle\sum_{i=1}^N \lvert S_i\rvert\leq 10^5$
• $1 \leq Q \leq 2\times 10^5$
• $1 \leq x_1
• $N,Q,x_1,x_2,\ldots,x_Q$ are integers.
• $S_i$ is a string consisting of lowercase English letters.

Input

The input is given from Standard Input in the following format:

$N$

$S_1$

$S_2$

$\vdots$

$S_N$

$Q$

$x_1$ $x_2$ $\ldots$ $x_Q$

Output

Print $Q$ lines. The $i$-th line should contain an instance of conforming $(K_{x_i}, L_{x_i}, R_{x_i})$, separated by spaces. If multiple triples satisfy the conditions, print any of them.

We have $M=16$. One possible sequence of triples that satisfies the conditions is $((1,1,1), (1,3,3), (2,2,2), (1,1,2), (1,3,4), (2,2,3), (1,1,3), (1,1,4), (1,2,2), (1,4,4), (2,3,3), (1,2,3), (1,2,4), (2,1,1), (2,1,2), (2,1,3))$. The corresponding sequence of $S_{K_i}[L_i, R_i]$ for these $(K_i,L_i, R_i)$ in this order is (a, a, a, ab, ab, ab, aba, abab, b, b, b, ba, bab, c, ca, cab).

Note that the sequence satisfies the conditions even if we swap the $5$-th element $(1,3,4)$ with the $4$-th or $6$-th one, so $(K_{x_1}, L_{x_1}, R_{x_1})=(1,1,2), (2,2,3)$ will also be accepted.

We have $M=5$. The sequence of triples that satisfies the conditions can be $(1,1,1), (2,1,1), (3,2,2), (3,1,1), (3,1,2)$ or $(2,1,1), (3,2,2), (1,1,1), (3,1,1), (3,1,2)$, for example.

Note that, for $(K_{x_i}, L_{x_i}, R_{x_i})$ that you print, the conforming sequence whose $x_i$-th element is $(K_{x_i}, L_{x_i}, R_{x_i})$ does not have to be common among different $i$; in other words, there does not necessarily have to exist a sequence whose "$x_i$-th element is $(K_{x_i}, L_{x_i}, R_{x_i})$ for all $1\leq i\leq Q$."
