Further, because the score-updating logic follows the check-then-act pattern, it is possible for two threads to "race" to update the high score, with unpredictable results.

另外，由于分数更新逻辑遵循check - then - act模式，因此可能出现两个线程“争夺”更新最高分，从而导致难以预料的结果。

Always check whether you have made right decisions from other's points of view. Think from different angles and never act impetuously. Then you can make right decision.

要经常从他人的观点出发去检验你的决定正确与否。要从不同角度去思考问题，不要感情用事。这样，你就会做出正确的决定。
