VSCode for LeetCode

用 VS Code 刷 LeetCode？真香！

Prerequisites

• VSCode
• node.js
• Java programming environment

Install VSCode extensions: Java development pack, LeetCode, etc.

Debugger config

First, create a file specifically for debugging, say Solution.java.

class Solution {
    public int func(int[] nums) {
        ...
    }

    public static void main(String[] args) {
        // Create a new Solution instance
        Solution solution = new Solution();
        // Create a test case
        int testCase[] = {1,2,2,3,1,4,2};
        // Get the answer
        int answer = solution.func(testCase);
        // Print the answer
        System.out.println(answer);
    }
}

Then open File>Preferences>Settings, uncheck java.debug.settings.forceBuildBeforeLaunch or add "java.debug.settings.forceBuildBeforeLaunch": false into .vscode/settings.json.

Next create .vscode/launch.json under the folder and add

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Debug (Launch) - Current File",
            "request": "launch",
            "mainClass": "${file}"
        }
    ]
}

Finally open Debug extension panel.
