<p>前言：暑假几乎花了一整个月备考PAT，期间因为调代码调到过深夜，做模拟题也曾做的心态有点奔溃，但总的来说这一段时间过的是很充实的，感觉自己的代码能力确实有提高不少，今年秋季PAT出的题都比较常规，侥幸拿了个满分（感谢姥姥手下留情），不过拿了满分后也并没有想象中的那样激动，更多的是一种怅然若失的感觉和冥冥中一种遗憾，我也说不清这种遗憾究竟是什么，感觉PAT也只是自己学习的长途中一个小的结点，它从某个角度上证明了前期努力的成果，但是它远不能成为对自己能力的炫耀，因为我知道自己能力还是有很多不足之处的，我觉得可以做到更好，这无疑需要更长期的努力。我愿把这次PAT考试作为一个新的起点，以此出发开始一段新的旅途，因为我觉得后面的风景会更美……</p>
<p>这篇文章是备考PAT过程中的一些笔记，记录下来作为一个纪念吧哈哈哈哈</p>
