　　年轻检察官高飞负责此案的起诉，一切的证据十分确凿；有记录案发生过程的现场录像、并且亲手抓获犯的刑警队长张小龙和死者的司机程克伟是案发的目击证人……铁证如山，凶手已难逃法网。赵培土踏前一步，望着永平帝道：臣以为，四灵是助皇帝镇守四方、守护天下臣民的。For codes of the same length, theoretically, the further the coding distance between any two categories, the stronger the error correction capability. Therefore, when the code length is small, the theoretical optimal code can be calculated according to this principle. However, it is difficult to effectively determine the optimal code when the code length is slightly larger. In fact, this is an NP-hard problem. However, we usually do not need to obtain theoretical optimal codes, because non-optimal codes can often produce good enough classifiers in practice. On the other hand, it is not that the better the theoretical properties of coding, the better the classification performance, because the machine learning problem involves many factors, such as dismantling multiple classes into two "class subsets", and the difficulty of distinguishing the two class subsets formed by different dismantling methods is often different, that is, the difficulty of the two classification problems caused by them is different. Therefore, one theory has a good quality of error correction, but it leads to a difficult coding for the two-classification problem, which is worse than the other theory, but it leads to a simpler coding for the two-classification problem, and it is hard to say which is better or weaker in the final performance of the model.民国初年，滇军旅帅杨兆麟突然患病不起，神医乔征被招入帅府，惊愕地发现杨兆麟是被人暗下毒药。杨兆麟临终为女儿杨月招婿纳夫，杨月却同时爱上了郑武和郑斐兄弟俩。最后杨月选择了郑斐，郑武妒恨交加，一个神秘的“哑巴”告诉了他的真实身世，他心潮难平，谋划了陷害忠良的奇冤。Looking at the INPUT chain in the filter table again, we find that the rule has been added. In iptables, the action is called "target", so the action corresponding to the taget field in the above figure is DROP.卿子，时人相褒尊之辞，犹言公子也。
