最近，Jvruo痴迷于一款格斗游戏。在这个游戏中，n个角色从左到右站在一个竞技场上，第i个角色的战斗力是a_i。对于每个操作，Jvruo将在竞技场上选择两个相邻的角色x和y进行决斗。如果 ax > ay，则 x 获胜，如果ax < ay，则y 获胜。如果ax = ay，则 x 和y 都有 50% 的获胜概率。胜利的角色将留在竞技场中，战斗力加倍;失败的角色将离开竞技场。

现在Jvruo将执行n-1个操作，经过n-1个操作后，戒指中将只剩下一个字符。显然，Jvruo 有 （n − 1）！操作模式。在所有这些操作模式中，哪些角色有概率坚持到最后并成为最终的赢家。

The first line contains a positive integer n(1 ≤ n ≤ 5∗10e5), which represents the number of the characters.

The second line contains n integers separated by spaces ai(1 ≤ ai ≤ 10e9), which represents the the combat power of the ith character.

The first line contains a positive integer m, which represents the number of the characters who have the probability to stay till the end and become the final winner.

The second line contains m integers in ascending order separated by spaces bi(b1 < b2 < …… < bm), which represents the the index of the characters who have the probability to stay till the end and become the final winner
