You and your friends have decided to create your own encryption scheme (bad idea). An encrypted message consists of 3 parts:
1) A character string pool
2) A interger array data
3) A interger array keys
To decrypt character i of the message, first find the smallest positive integer k such that (data[i] * k) % key[i] = 1
Above % denotes the modulus operator. Character i of the message will be character j in pool, where j is given by j = k % (length of pool)
There are many tests.In each test there are four lines,the first line is the pool,the length len(1<=len<=100000),the second line is a interger n(1<=n<=100000),then the third line there are n interger in array data.The forth line also n interger in array key.
Output the decrypted string. Constraints will ensure that the ith element of data is relatively prime to the ith element of keys. In other words, the largest positive integer that divides data[i] and keys[i] will be 1, for all i.
