perhaps a user space implementation. i am trying to avoid
copying data from kernel to user space back and forth in read and write data
from and to the socket. No blocking thread model. Thank you very much! |

发帖数: 2024 | 4 最大直方图题，
发现原来题目有限制，每一个小矩形最大高度，可以到1E9.
如果用statck什么的，内存会不够用。
觉得原来的题目，是说矩形高度大到内存放不下。
有没有link？
多谢了。 |

发帖数: 21 | 5 Looks like there are 8 bytes padding between a[] and b[] and statck grows
downwords.
so:
b = &a[0] - 20 - 8
t = &a[0] - 20
t = b + 8
so *t = 300
* (t + 1) = 400 |
