Answer = number of Palindrome sub-series-palindrome substring number.The number of palindrome substrings can be calculated by Manacher in $o (n) $ time.For the number of palindrome subsequence, F[i] is the logarithm of the character with the symmetry center of I, then its contribution to the answer is $2^{f[i]}-1$.For two numbers $1\leq I\leq j\leq n$, if A[I]==A[J], then they have 1 contributions to f[i+j].So you can calculate the contribution of the match by enumerating the current character a

The use of packet tracer to do experiments so long, but do not know how to add, also did not pay attention to, today for an experiment need some modules, just remember to add, but when added, but it shows: Cannot add model when the "" is on. Studied the next, as if there is no place to turn off the equipment, is it the use of command? Check it out, there is no such order. So in the open router interface, go to the physical, see a power button, will be

Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and protect the host network.Nat has static NAT (internal address and external address one-to-one) and dynamic NAT (internal address pool and external address Pool A-do)This time we'll

Network address port Conversion NAPT is a very familiar way of transformation. NAPT is commonly used in access devices, which can hide small and medium-sized networks behind a legitimate IP address.Unlike dynamic address NAT, NAPT maps An internal connection to a separate IP address in the external network, adding a TCP port number selected by the NAT device to the address.This time, let's get to know napt.Configuration ideas1 Configure the router's interface IP address, note the network segment
