The Power of Insistence

Last night, I watched a tennis game, it was the US open, because there was a Chinese female player came to the semi-final, so I stayed up to watched the game. Unluckily, she was injured twice, though she still wanted to finish the game, her body situation did not allow her to do so. Her insistence moved so many audience, they gave her the biggest applause.

The power of insistence is great, it will help you set free your potential and keep move on. Just for the players, they will face all kinds of incidences now and then, but the will to insist will make them finish the game. Sometimes, people win the game not because of their excellent skills, but their strong will. Those who can stick on to the final line will win people’s applause.

What’s more, when people insist to finish the game, it is the respect that they show to their opponents. Their spirit deserves people’s applause. Insistence is a merit, we should keep it, no matter what we do, we must remember to insist.

努力的看代码中

我运行了没死循环啊，但是输入的是字符串，还有case语句后面加上break哦。
还有就是，运行停一下看看结果。
