Answer 1

def str_concat(A, B, C, T):
    res = ''
    for Ti in T:
        if Ti == '1':
            res += A
        elif Ti == '2':
            res += B
        elif Ti == '3':
            res += C
    return res


def main():
    A = input()
    B = input()
    C = input()
    T = input()

    res = str_concat(A, B, C, T)
    print(res)


main()
