发帖数: 6098 | 1 不知写个non-recursive的DFS会不会好点,减少system stack call.
要用一个stack，但因为我想打印出路径，所以觉得用一个deque来保存各个点比较好点。
void FindAllPath(G, source, dest)
deque d;
d.push_back(source);
//这里还要一个数据结构visit表示点是否访问过，跟DFS那里一样。
while(!d.empty())
u = d.back();
for(each v in u's neighbor)
if( v == dest)
print path (that is from d's front to end)

d.push_back(v);

发帖数: 1136 | 13 It's the Cisco thing. I think it is some logical interface with an IP/mask to indicate a network. Each physical port can be associated with a SVI. Basically it is a way to tell control plane kernel that if dest MAC matches the assigned ports, and dest IP matches the SVI, dispatch the packet to control plane daemons, based on port numbers, that are listening on the IP address. |

发帖数: 3612 | 15 我也回答一下，
pc1 ping pc2 能通，因为pc1一看dest ip在自己的网段里，
没什么犹豫就开始试验,
1. 发ARP，(ARP 的dest MAC is ffffff)
2. pc2 回答arp 告知pc1自己的 mac
3. pc1 send out ping icmp.
4. pc2 应答 ping。
PC2应答的时候是不需要判断对方ip的网段的，因为他不知道对方是router或pc.
这样就完成了pc1 ping pc2。
但是当要求pc2 ping pc1时， pc2一看pc1不在自己的网段，
如果没有default gateway 它直接就放弃了。
如果有default gateway, 它会发给gw,
但是gw不会再把这个请求发回来同一个网段。
而且他不会发(broadcast) arp去请求pc1的 MAC. 因为不在一个网段。
所以pc2不会知道pc1的MAC.
对不对？ |

发帖数: 597 | 16 我以为只能转换函数的返回类型呢。
怎么实现转换参数类型的呢？能详细说一下后台怎么处理的么？
这个问题来源于C++ template, writen by Davice Vandervoorde. Section 4.2
Nontype Function Template Parameters. It provides a function
std::transform(source.begin(), source.end(), dest.begin(), addValue)
It says that compiler may have problem doing parameter deduction in this
form, and gives another form:
std::transform(source.begin(), source.end(), dest.begin(),
(int(*)(int const*))addValue)
I'm totally lost about what he's talking about.

要比较就比较11款的odyssey和sienna；

你要是喜欢abuse车的话，买sienna的；
简单说吧，sienna拖车能力强（不是engine，是transmission比较heavy duty;honda的
tranny差点，也是大部分ody owner的心病）；11款的suspension很硬，比ody还硬；
toyota的timing chain, honda还在用落后的timing belt，5-6年后还要换；
ody的优点就是内饰好，做工细腻，很多小东西做的贴心。
ody纵向空间好，sienna则更宽。
