Are you preparing for a coding interview? Or for a job interview? Are you looking for some problem to solve?

This app can help you. It has a lot of different problems in different groups, so you can choose one or another to solve. If you don't know how to code, you can still use this app to learn. You can choose to use your own code or to download the problem from GitHub.

With this app, you can find all the problems and solutions for your profile in a few seconds. The problems are divided into two categories: data structure and algorithm. If you want to find a solution to a particular problem, you can just search by its name. If you don't know the name, you can search by its ID. The app has an interactive guide to help you with your coding, so you don't need to learn how to code by yourself. The guide has different sections for data structure and algorithm.
