dod-v3.zip - Tablesaw is an in-memory table containing a variety of data tools and column oriented storage formats.The idea was that no one would perform distributed analysis for small tasks, and everyone could interact with 2 million row-level tables on a single server.
Tablesaw enables you to execute a variety of rules to check display layout, data priority, or extend control to a specific user for data display and interaction.With its help, we can import data with RDBMS and CSV files, add and remove columns, perform mapping and specification operations, or save tables in a compressed column storage format.,2019-11-13 09:16:00,下载0次
dod-v2.zip - If you want to interact with data in a cool way, Dex is not to be missed.It helps us extract, transform, and visualize data with predictive capabilities.You can publish visual results as 3D or other HTML variables.
Dex allows us to generate over 50 different visualization patterns, including world maps, participation schedules, network usage, etc.You can also build complex statistical and predictive analysis systems by combining R with its operational examples.,2019-11-13 09:15:32,下载0次
dod-v1.zip - The strman-java library is a set of Java 8 libraries designed specifically for handling strings.Because it is available for Maven, you only need to add associations to the selected build tool.
If you've used Kik and heard of the leftPad problem it encounters, Strman might be a better choice -- it returns a new string of a certain length and automatically populates the beginning.It also provides a complete list of capabilities, including attaching strings to values, extracting characters from specific directories, and using strings to return arrays between start and end.,2019-11-13 09:14:59,下载0次
网络编程.zip - Java network programming is mainly involved in the content of Socket programming, then what is Socket?Simply put, a Socket is the endpoint of a logical connection between two hosts.TPC/IP protocol is the transport layer protocol, mainly dealing with how the data is transmitted in the network, while HTTP is the application layer protocol, mainly dealing with how to wrap the data.Socket, essentially a set of interfaces, is the encapsulation and application of the TCP/IP protocol (at the programmer level).,2019-11-13 09:07:18,下载0次
二叉树.zip - A binary tree is a data structure that evolved from a tree, and all the terms above apply to binary trees.A binary tree is different from a tree in that every node of the tree (except the terminal node) is allowed to have several subtree branches.The binary tree can only have left and right subtree branches, that is, the degree of nonexistence is greater than 2 nodes.,2019-11-13 09:00:58,下载0次
