I didn't understand the first question of today's tragedy. Well, I won't do it. Question B is the simplest and can be published.   The idea of this question is actually to check the set. First, define an array st to indicate the current state.

In the process of science and technology thesis writing and dissertation, to understand the current domestic and foreign research status and determine the research direction, we need to search the thesis database. As the saying goes, a good start is

This is a difficult question to think about. During the competition, I wanted to think of splay as a decisive tragedy. Only tonight I suddenly found that I could use a tree that can be merged. The idea is to maintain a binary tree. Each time an

DP finds the length of a number that is connected to itself on the left and right of a [I], and then multiply it by a [I]. The biggest product is the answer. # Include # include # define ll long # define n Limit 5int I, n, T; ll A [n], L [N], R

During the competition, the code on the scene was messy, which was a sorted version. For simulation questions, pay attention to the input of string data and use recursion to solve overlapping (diffusion) parts. // Template start # include # include

Codeforces should be easier to compete in TC games, but it is a pity that the third question was not shot that night. It may be that the time was not enough, stuck in the first question for too long, a little tragedy ....   A. Rind Road   This

In many cases, we can use one or more Integers to compress the variable state, which is conducive to space optimization. Although there is little benefit to the amount of code, however, when there is a large amount of data, it can still have a

Okay .. My second question is still hanging. If you forget it, just ignore the second question and paste the ACD Solution ideas.   If you don't talk too much about the question a, you can directly simulate it. Use array a to represent D at the
