while True: try: t,n=list(map(int,input().split())) stri="" for i in range(t): stri=(stri+input()) x=list(map(int,input().split())) for j in x: print(stri[j-1],end='') k=input() except EOFError: break
for j in x: print(stri[j-1],end='') k=input()
for j in x: print(stri[j-1],end='') k=input() 全部輸出完要換行這行刪掉
