How to implement a quicksort algorithm in Java?
Article Introduction:Quicksort is an efficient sorting algorithm with an average time complexity of O(nlogn), and its core lies in the division and governance strategy and recursive logic. 1. Select the reference value (usually the last element); 2. Place the number less than or equal to the reference to the left and the one greater than the right; 3. Perform the above steps recursively on the left and right subarrays. The key to implementation lies in the partition function, which returns the final position of the reference value and correctly divides the array, while handling duplicate elements and swap operations. Optimization suggestions include avoiding the worst pivot selection, switching insertion sorting of small arrays, and considering the use of merge sorting of object arrays in Java to maintain stability. Mastering these key points can achieve an efficient and usable quicksort.

What is the difference between INNER JOIN and LEFT JOIN in MySQL?
Article Introduction:INNERJOIN returns only matching rows in the two tables, while LEFTJOIN returns all rows in the left table, even if there is no match for the right table. For example, when using INNERJOIN to connect users and orders tables, only users with orders are included; while LEFTJOIN contains all users, and the order field for users who have not placed orders is NULL. When selecting JOIN type, you need to pay attention to: use LEFTJOIN and filter NULL values ??when searching for unmatched records; avoid duplicate data selection INNERJOIN; pay attention to the data bloating that the aggregate function may cause; always check the ON condition to ensure correct association. Understanding how both handle non-matching rows is the key to using correctly.
