Select A[j] To join an existing paragraph, 3). Select A[j] To start a new paragraph, that is because each paragraph here must be continuous, and if so, but discontinuous, discontinuous is not the new Is the paragraph coming out again?Transfer:

This question is to find the M-segment sub-segments, and require these sub-segments to be added up and the maximum, maximum, and plus versions. However, the meaning of the question is really hard to understand. X and Y are not clear. When I knew the question, I began to solve the problem. This must be a dynamic programming method. The process of dynamic programming is not difficult to write. The key is abstract thinking. The minimum condition here
Title: A string with a length of M inserts n plus signs for minimum and. For example, string str= "123456", n=2, Output 12+34+56 and 102, and Output 2 4, which is the plus position. Here is the idea:The implementation process is mainly the idea of interval DP, wherein the state transfer equation is dp[i][j] = min (

Question: give you a tree with N nodes. The edge of the tree is the weight value. You need to find the maximum distance between each node on the tree and other points. Find the longest segment from node 1 to the maximum node N value so that the node with the maximum and minimum values in this segment is less than or equal to M.
There are two solutions to the first problem. The first simple method is that the biggest value in the distance between each point and other points must be one of the dis

Question:
Extra Binary Tree[Problem description]Set the ordinal traversal of a tree with N nodes to (l, 2, 3 ,..., N), where the number is 1, 2, 3 ,..., N is the node number. Each node has a score (all positive integers). Note that the score of node I is Di. The tree and each of its Subtrees have a plus score, the method for calculating the extra points of any subtree (also including the tree itself) is as follows:Bonus points for the left subtree
