It's time for TLE to die. It's just over n optimizations, and it's full of tears. Question: A_1, a2... A9, AI indicates that there is an ai I. Ask how many different numbers are composed of these numbers and what is it after mod 1000000007. Question: First, the method is clear: Number of BITs, which indicates the position of a certain number. If there is an L-bit, the number I is on the J-bit, then the contribution of I on this bit is I * 10 ^ (J-1) *

First paste a TLE code... # Include Although it was me, it was my attempt. Although TLE is... helpless .. First, define the number of reverse orders: The number of Ai> Aj in a string of numbers. Conversely, when I> j, the number of Ai Generally speaking, it is the number of numbers that are larger than Ai before. Here is a brief description of my formula. | ...... | AB | ...... | Assuming that AB is the

At the beginning, we had time to play the BC game at night. The data on this topic is big. Although I have noticed it, it's still TLE. ... Start with set for TLE Then we use vector for TLE. It is discovered that gcd (x, y) should be obtained first, which can reduce a lot of Traversal 1 #include View code 1 #include View code 1 #include View code Post all the c

The topic probably means: input n,m,n represents n points, then enter the distance between n points (N*n matrix), then M inquiry, input a,b,c if there is a C point between the shortest path between a and B, output yes, otherwise the output noThe game did not make it out, after the game sail brother a on-demand to know .... When I write, I directly use the Floy algorithm to find the distance and record the path. Then tle to die ... I was surprised that

It was exactly the same as Noip's, and I rewrote the code a bit more clearly.Ideas See http://blog.csdn.net/vmurder/article/details/38734663But I still have to say it again.First of all, we build the minimum tree, this is not proof, because in accordance with the Kruskal map, each traversed an edge, it is equivalent to some of the inquiry between the road, and must be the edge.And then it's YGYLCA.
