while True:
    try:

        b = [int(x) for x in input().split()]
        c = input().strip()
        if len(b) > int(a): break
        else:
            if int(c) == 0:
                print(" ".join(map(str,sorted(b))))
            elif int(c) == 1:
                print(" ".join(map(str,sorted(b)[::-1])))
            else:
                break
        
    except:
        break

tips:

不想这么写sorted(b)[::-1] ,可以考虑sorted(b,reverse=1) (0为默认正序,1为倒序)
