Filling in each cell takes constant time - just a bounded number of additions and comparisons - and you must fill in mn cells.
填充每个单元格需要的时间是恒定的—只需有限数量的相加和比较—必须填充mn个单元格。
The LOGGING constant in Listing 1 should be TRUE if you want this logging to work, but leave it FALSE when it is running on the cell phone, as the performance hit can be significant.
如果希望启用这个日志记录功能,那么 清单 1 中的 LOGGING 常量应当为 TRUE,但是如果是在手机上运行的话,应当将其设为 FALSE,因为性能损失是非常明显的。
To get any location in memory, to get to any value of the list, I simply have to say which element do I want to get, I know that these things are stored in a particular size multiply that index by 4, add it to start, and then it's in a constant amount of time I can go to that location and get out the cell.
取得列表中的任何一个值,简单说来,想要取得列表中的任何元素,我知道这些元素存在特定的大小中,把下标乘以4,加到start上,然后定位到内存单元,并取出值就是固定的时间了,好的,如果元素以固定大小存储。
