Will's Message
By Ricardo Oliveira, UFPR 
Brazil
Timelimit: 1
After an intense match of a RPG game at the house of one of his friends, young Will disappeared mysteriously! Everyone is desperately looking for him everywhere. Meanwhile, strange things are happening at your home. One of these things, however, allows you to communicate with the boy!
There are exactly 26 bulbs attached to the wall of your living room, numbered from 1 to 26 from left to right. Also, there is a letter drawn in the wall bellow each bulb. When Will wants to send you a message, he will (mysteriously) blink the bulbs corresponding to each letter of his message, one at a time. For example, if he wants to send you the message HELP, he will blink, in this order, the bulbs above the letters H, E, L and P.
Given the letter associated to each bulb and the order of the bulbs Will blinked, decipher the message he sent!
Input
The input contains several test cases. The first line of each test case contains a string with exactly 26 uppercase letters, containing all letters of the English alphabet. The first letter in the string is associated to bulb 1; the second letter in the string is associated to bulb 2; and so on. The next line contains an integer N (1 ≤ N ≤ 104), the number of bulbs that were blinked. The third line contains N integers li (1 ≤ li ≤ 26), indicating the bulbs that were blinked, in that order.
The input ends with end-of-file (EOF).
Output
For each test case, print a single line containing the message sent by Will.
