放到LeetCode上run code 與 submit solution結果不同，點進問題解說中看到
First, please check if you are using any global or static variables.
They are Evil, period. If you must declare one, reset them in the first
line of your called method or in the default constructor.
Why? Because the judger executes all test cases using the same program
instance, global/static variables affect the program state from one test
case to another. See this Discuss thread for more details.
這段英文有看沒有懂，有大大可以指教嗎？
感謝指教
