There is a funny car racing in a city with n junctions and M directed roads. the funny part is: each road is open and closed periodically. each road is associate with two integers (a, B), that means the road will be open for a seconds, then closed for B seconds, then open for a seconds... all these start from the beginning of the race. you must enter a road when it's open, and leave it before it's closed aga
Question: equation x = p * floor (x ÷ K) + Q * Ceil (x ÷ K) given X and K, evaluate a group of valid p and q.
Analysis: number theory. Set x = m * k + N (where n = x mod k );
If n = 0: x = m * k, floor (x ÷ K) = Ceil (x ÷ K) = M, x = p * m + Q * m, make P = K, q = 0;
If n = 0: x = m * k + N, Ceil (x ÷ K) = m + 1, floor (x ÷ K) = M, x = (p + q) * m + Q,
In this case, make p + q = K, q = N (because n
Note: p and q can be exchanged when X is divisible by K.

Train of Thought: First, you can get the cost of the edge by finding the bridge through Tarjan (using the nature of the Bridge), and then the second answer! For each vertex, if a son cannot maintain the edge, it is not feasible. Otherwise, try to let the son maintain the edge right. If not, he can only let the father bear it.

Given a three-dimensional octal digital, 0 represents an empty position and asks if it can be sorted back.
Solution: for the case where n is an odd number, consider the reverse logarithm of the three-dimensional octal digital to consider the case where the State goes down, except 0, and the even number, consider transferring the position of 0 to (

Obviously, the intersection height and the bottom edge length are inverse proportional functions, which can be solved using two points.
Use the intersection point to locate the height of the two sides.

General steps for using VA macros:
Vsptr (Char * Format,...) // Remember the format here

Va_list argptr;
Va_start (argptr, format); // enables argptr to point to a bucket starting with format
Va_arg (argptr, type); // returns the current parameter of the parameter list pointed to by argptr, and causes argptr to point to the next parameter in the parameter list
...
Va_end (argptr); // stops, releasing the memory space occupied by argptr
Ndk r8b was installed recently, but a large number of warnings are displayed when ndk-build is started in cygwin. So, Google it first to find the fuzzy answer. We can see from the ndk download website that ndkr8b has indeed updated the C ++ compiler. In addition, according to the introduction on the internet, there will be no such warning when using ndk R8. Well, I didn't try it. I guess OK (because the author said he did it himself ).The following content is also obtained:David Turner (from the
The difficulty of the provincial competition in the year before was that the stone was not well handled.
Later I read the summary of Yang Shen's provincial competition and found that this stone is here, because there are only four or five sub-members, it is enough to deal with violent DFS. First, we regard the stone as a common obstacle, perform a full graph of DFS or BFs, find the available points, and then each time the DFS explores a new point in a new area, we can figure it out.
