相比第一次作业,第二次作业中大家对于”阅读《构建之法》并提出问题”这个部分普遍比第一次作业有进步,很多同学提的问题都不错 👍
比如这个同学提的这个问题:
5.在阅读《构建之法》16.1.2 迷思之二:大家都喜欢创新 中的
如果使用QWERTY键盘,那么只有10%的英语单词能在手指不离开键盘中列的情况下敲出来。但是如果使用Dvorak键盘布局,你可以在键盘中列打出60%的常用单词!这样会减轻手指和相关肌肉的负担,减少劳损,同时加快打字速度。......但是,长期以来,人们已经习惯了QWERTY键盘,所谓先入为主。
我有一个问题:当前中国人最离不开的软件微信,是否正在成为中国的“QWERTY键盘”?这样的软件存在是否会打击行业创新的积极性呢?
思考:我觉得微信不是中国的“QWERTY键盘”,至少现在不是,毕竟微信有痛点,也不是不思进取。微信确实给聊天软件的创新带来了巨大的阻碍,垄断行业让创新很难被注意,但是有意义的创意被行业注意只是时间问题,不思进取,被行业淘汰也是时间问题。
本次作业很多同学的编程部分得了0分,主要存在以下问题:
-
文件编码不规范。
-
导入了第三方的包。
-
源码目录不正确。
-
主函数所在文件的文件名不正确。
-
没有注意输出文件的格式,多了一个空格,或者多了一个空行,导致输出结果和标准答案对不上。
-
输入输出文件的位置没有处理好,这个问题没有什么好商量的,基本上约等于你考试每题都做对了,但是答题卡填错了位置。
我们放宽了性能要求(其中超时时间已经延长到2分钟),就是尽量考察同学们的编程正确性,评分严格对同学们来说不是坏事,希望可以让同学们养成对编程严格要求的好习惯。
注:对于分数有疑问的同学,请在明天下午(2021-03-22)1点之前反馈给老师或者助教这边
