GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window

• https://leetcode.com/problems/maximum-subarray/ # Close enough
• https://leetcode.com/problems/minimum-size-subarray-sum/

XAMPP - Replace MariaDB with MySQL

Since XAMPP 5.5.30 and 5.6.14, XAMPP ships MariaDB instead of MySQL. MariaDB is not 100% compatible with MySQL and can be replaced with the "orginal" MySQL server.

Backup

• Backup the old database into a sql dump file
• Stop the MariaDB service
• Rename the folder: c:\xampp\mysql to c:\xampp\mariadb
