requires only one additional variable to temporarily store the data items at the time of exchange. So there is no comparability of the size of the memory footprint. The number of times to insert a sort is still the square of N, but in general, it's a bit faster than the bubble sort, faster than the sort selection. It is often used in the final stages of a complex sorting algorithm, such as a quick sort. Algorithm: After i-1 after processing, l[1..i

Insert record of Java databaseThere are 3 scenarios for inserting data table recordsI. Using the Statement object The syntax for implementing SQL statements that insert data table records is: Insert into table name (field name 1, field name 2,......) Value (field value 1, field value 2, ...) For

Label:In this note, we'll see how we can use the JDBC API like statement and PreparedStatement to bulk insert data into any database. In addition, we will try to explore scenarios such as working properly when memory is low, and how to optimize bulk operations.First, BULK insert data into the database using the Java JDBC Basic API.Simple batch-Easy batchingI call

A heap can be divided into a maximum heap and a minimum heap. The maximum heap is a complete binary tree with the value of> = its left and right children (if any. The minimum heap is the Complete Binary Tree with the value of The sequence of n elements {k1, k2,..., kn} is called heap only when and only when the following relations are met. Three basic operations on the heap (the largest heap is used as an example below ):(1)

As the name suggests, inserting sort is to insert the element that is currently being sorted into a list that is already in order . A very vivid example is to grab a poker hand and insert
