Berkeley CS 61B Data Structures(in Java) Project1 加分+讨论帖

partI 的结果~看到图片好有成就感~

感觉part 4,花的时间太多了，花了4个小时，写了一个两百行的if else，最后怕思维混乱，还辅助以思维导图，醉了。。。。求加分，求加分。

PART4实在不会，交前三个。花了很长时间

请问project1里面的data.gz打不开怎么办啊

特么 partI 做到最后  发现图形怎么打开都是黑的。。。没用blur 直接用他给的method打开都是黑的 求破啊

请斑竹把这一楼删除了  太长时间没法编辑了

project终于做完了  花了很长时间。。。做的也不专心。。。刚开始特么特地看RGB 像素矩阵啥的 还有tiff 发现白费时间了  理解好了readme就行了。。。。这个有些地方还没懂 ，比如iterator我没用啊。。。。。就构造了一个而已 OTL。 我感觉这个不太好理解的是为啥每次RGB值都一样。。。可能是直接对灰化的图像处理吧  反正不懂。。。上图Testing one-parameter RunLengthEncoding constuctor on a 3x3 image.

还是自己太渣了 码的过程中概念问题出了好多bug 然后debug又de了好长时间 幸亏这段时间闲

搞了一整天。。还好留给我3个多小时准备跨年

樓上的朋友, 如果你用的是eclipse
可以參考一下下面圖示的

谢谢你的介绍，很有用！

纠结了几天， 把题目读了又读，无数次想放弃，  但最后还是把part I 搞掂啦。
明天再继续加油后面的题目

拖了好久，总算把project1做完了。自己刚开始没有注意到这个RLE要求是逐行扫描像素。。。写成了逐列扫描像素，压缩后的图始终出不来。同时通过这次project也让我更加重视不同类型数据赋值的问题，自己好多bug都是和这个有关。
