Problem 6 (200pts)

实现always_roll，这是一个高阶函数，它接受一个骰子数n并返回一个总是掷n个骰子的战略。因此，always_roll(5)将等同于always_roll_5。

在编写任何代码之前，请解锁测试以验证您对问题的理解：

python ok -q 06 -u

解锁完成后，开始实现您的解决方案。您可以使用以下命令检查正确性：

python ok -q 06

def always_roll(n):
    """Return a strategy that always rolls N dice.

    A strategy is a function that takes two total scores as arguments (the
    current player's score, and the opponent's score), and returns a number of
    dice that the current player will roll this turn.
