Master LeetCode Problem Solving with VSCode: A Complete Setup Guide

Many developers use VSCode for coding practice because of its rich plugin ecosystem, attractive UI, and built‑in debugging support for most languages with minimal configuration.

Download and Install

Visit the official VSCode website, download the installer, and run it. During installation, enable the options that add VSCode to the command line and allow right‑click editing of files or folders.

First Use

When VSCode launches for the first time, a welcome screen appears, offering quick access to recent files and folders. Press Ctrl+Shift+P to open the command palette, where virtually every function can be invoked.

The interface layout is illustrated in the following screenshot, showing the positions of the main components.

Enter playground in the command palette to open a help view that introduces basic VSCode features.

Start Solving Problems

Install the LeetCode extension from the VSCode marketplace. After installation, click the LeetCode icon on the left sidebar, then the globe icon to select the Chinese site.

Log in with your LeetCode credentials. You can browse tags such as “Dynamic Programming,” select a problem, write code in the editor, and click Submit to see the result on LeetCode.

Basic Language Extensions

For C/C++ development, install the C/C++ extension to get formatting, debugging, code navigation, and IntelliSense.

For Python, install the Python extension, which offers similar features plus richer ecosystem support.

As you become accustomed to VSCode, you’ll find plugins for most development needs, and you can even create your own extensions if required.

Although VSCode once felt sluggish, years of optimization have made it a fast and versatile tool for everyday coding tasks.
