is 7 bits :As can be seen, the string length of 7 bits, the generation of Covin ciphertext, are not duplicated , the basic can meet most of the situation, more I did not test, we are interested to test the number of bits generated when the duplication occurs. The advantage of this approach is that the longer the original string length, the resulting volume of ciphertext that will not be duplicated will be larger, and you can adjust it as needed.However, the only disadvantage of this way is that

Title Link: http://poj.org/problem?id=1511Test instructions: gives n points and n a forward edge, all points to the source point 1 back and forth the shortest possible sum (guaranteed each point can return to the source point 1)The problem is relatively simple is the number of sides and points a bit more so you can use dijstra+ priority queue so complexity can be to V*logn#include Poj 1511 Invitation Cards (Dijstra optimization)

Test instructions: There is a starting site, from here to send n students to the rest of the N-1 site invite people to CSS, and then back to the CSS, so that the total cost is minimal. Note that you can only send one at a time, return each time can only send one, and each road is one-way.Analysis: This is equivalent to a graph, we only need to call the SPFA algorithm two times, the first time to find out the initial site (here is 1) to the minimum cost of all other sites, and then add, the secon
