I haven't written tree dp for a long time... in the past, we found leaf nodes first. using queue maintenance... this learning method of vector dynamic array + DFS rollback .. I feel the idea is clearer... The first question about the question... the maximum number of people that can be invited .. so easy... very basic tree-like DP .. dp [k] [0] indicates the maximum number of users who do not select k points in the k-root subtree... dp [k] [1] indicates the k point .... The key is that the quest

Use a hashed connection to obtain optimal performance from a DB2 Universal DatabaseThe DB2 UDB optimizer can select different methods when executing connections: by default, it selects between nested loop join and merge join. When special environment variables are set, you can also select hash join ). Hash join can significantly improve the performance of some queries, especially in the Decision Support System (DSS) environment, because the query in t

The optimal algorithms for finding the maximum and minimum numbers, and the minimum number of comparisons required for finding the two largest numbers We know that looking for a maximum number in a data set with a capacity of n, no matter what comparison algorithm is used, it should be at least n-1 times, even if it is sorted by a competition, it will be n-1 times, otherwise, you cannot guarantee the maximum number. So what is the minimum number of co

The optimal triangle division and matrix concatenation are both of the same issues. They all belong to the expression brackets. A matrix concatenation is a group of matrices that multiply, but different sequences have different numbers of multiplications. This requires us to find the execution order with the least number of multiplications. The optimal triangle division and matrix concatenation of a con

Today, we also caught up with Samsung's TB crash, but there was no result in finding a solution on the Internet. Many of our friends were jealous of Samsung's product quality and did not provide a solution. We can't just look at these two good monitors, so it's like shaking a "non-optimal mode" box, so don't worry about it, turn off the power. As a result, after more than an hour, the system returns to normal after it is started (surprise ). Post imme

Title:Given an array of non-negative integers, you is initially positioned at the first index of the array.Each element of the array represents your maximum jump length is at that position.Your goal is to reach the last index in the minimum number of jumps.for example:given array A =[2,3,1,1,4] the minimum number of jumps to reach the last index Is2 . (Jump1 step from index 0 to 1, then3 steps to the last index.) idea: This topic is similar to the jump game mentality. Only this time, we have

The network access control optimization solution is worth exploring. Many people may not know about network access control yet. It does not matter. After reading this article, you must have gained a lot, I hope this article will teach you more things. Network Access Control Based on hardware, software network access control based on proxy, software network access control without proxy, or dynamic network access control can all improve network security. To select the right solution, IT managers n

How to set the optimal 4G memory virtual memory ?, 4G memory virtual memory Memory is one of the important components in the computer and serves as a bridge to communicate with the CPU. So, do you know how much virtual memory should be set for the 4g memory of the W7 system? Within 4 GB of physical memory, the virtual memory is generally set to 2 times of physical memory, for example, 1 GB of physical memory is set to 2 GB of virtual memory. In thi

MySQL 5.6 5.7 optimal configuration file template (my. ini), mysql5.6 Inside has compiled a new configuration file template based on MySQL 5.6 and 5.7, which basically covers 90% of the optimization options. You only need to make slight modifications based on your server configuration, for example, InnoDB buffer pool size and IO capacity (innodb_buffer_pool_size, innodb_io_capacity ). Note that this configuration file does not need to be modified. Yo
