• Learn programming with the best code recipes. • Kotlin: - How to get a substring? - How to declare a generalized method? - How to perform a database query? • SQL: - How to combine multiple tables in a single query? - How to sort the result of grouping data? - What types of data are there in SQL Server? • The best examples of code from books and specific internet resources are selected in the app. Finding the best solution on the internet can take hours of work. Ready-to-use and tested "recipes" for code are included in the app. • The app is a great tool for passing exams or preparing for interviews. It helps you study the typical tasks you might face. • One app for iOS and macOS. Buy once and use it on your phone, tablet, or computer. • Quick search of the correct example by code or name of topic. • All examples in the app are available offline. The app can be used when an internet connection is not available. • As a developer, I use this app when I need to quickly remember how to solve a given task in SQL or Kotlin. If you can help to translate the app into your language, please contact me by email. In the application, some examples are available for an additional fee (approximately 45%).
