The first construction started after the year of the snake. I will discuss a simple Amazon pen exam this time. I will first release my own solution. You are welcome to reply to better algorithms. I will update them to my post. Learn together! The question is from GeeksForGeeks. It was the memoir of a ox who successfully applied for Amazon after 10 rounds of written tests and interviews and gave back to the public. There are several interesting questions. Let's take a look. It may have been a lon

Note: If you think about this problem, it's a big mistake to compare elements.Of course, this algorithm is not optimal, it does not represent universality. But can be extended, the overall or this idea, is nothing more than "fill in the blanks" operation Public classOrderlink {/*** An array of 65,535 numbers that do not duplicate integers greater than 0 (that is, all the non-repeating integers in the 0~~65535, the

Development Requirement: the person who makes the delivery order must maintain the same delivery position for the same order. It is designed to change all rows to the same position as the first line before saving. If inconsistency is found during shipment, the system will check if it does not pass the bill. The user exit is as follows: Modify userexit_save_docum

Label: SQL Union and SQL UNION ALL usage difference efficiency and the problem with order by and group by mates SQL Union and SQL UNION ALL usage SQL UNION operator The UNION operator is used to combine the result set of two or more SELECT statements. Note that the SELECT statement inside the UNION must have the same number of columns. The column must also have
