我正在编写一个名为TypeBetter的程序，共有3种模式。简单来说，您必须准确输入25个单词，以免分数下降。除了中型句子（10）和硬性段落（5）外，Medium和Hard都一样。
“简易”模式效果很好，但是当我尝试执行“中等”或“困难”模式时，程序会立即打印出数组的第一个和第二个元素。

"Be here on time and ready to learn.",
"The weather is very nice today, but I wish the wind would die down.",

the moon in the Sea of Tranquility, a basaltic flood plain, on July 20, 1969. The moonwalk took
place the following day. On July 21, 1969, at precisely 10:56 EDT, Commander Neil Armstrong

largest animals on the planet, whereas lakes support much smaller forms of life. When it is time

past her usual table and sat down right next to me. Even though I was new, I had already figured
out who Karen Watson was. She was popular. Pretty soon, all of Karen’s friends were sitting
there right next to me. I never became great friends with Karen, but after lunch that day, it
seemed like all sorts of people were happy to be my friend. You cannot convince me that Karen
did not know what she was doing. I have a great respect for her, and I learned a great deal
about what it means to be a true leader.",

game of the new season; I believe there is much to be excited about. Although they lost, it was
against an excellent team that had won the championship last year. The Blue Whales fell behind
early but showed excellent teamwork and came back to tie the game. The team had 15 hits and
scored 8 runs. That’s excellent! Unfortunately, they had 5 fielding errors, which kept the
other team in the lead the entire game. The game ended with the umpire making a bad call, and if
the call had gone the other way, the Blue Whales might have actually won the game. It wasn’t a
victory, but I say the Blue Whales look like they have a shot at the championship, especially if
they continue to improve.",
"Sunset is the time of day when our sky meets the outer space solar
winds. There are blue, pink, and purple swirls, spinning and twisting, like clouds of balloons
caught in a whirlwind. The sun moves slowly to hide behind the line of horizon, while the moon
races to take its place in prominence atop the night sky. People slow to a crawl, entranced,
fully forgetting the deeds that must still be done. There is a coolness, a calmness, when the
sun does set."

我花了大约15分钟来格式化您的代码。然后我意识到您的错误是由于您没有在变量hard中定义字符串而引起的。将hard的定义更改为以下内容。那应该可以修复您的代码。
