Leetcode 75 Notes

Exercises taken from the Leetcode 75 interview problem compilation. Each exercise folder has the following files:

$ tree ,<exercise-name> 
,<exercise-name>
├── index.js        # Solution implementation
├── package.json    # Contains execution scripts
├── README.md       # Problem description
└── test.js         # Test cases implementation

Usage

To streamline the setup process for each exercise, you can automatically inject the common scripts defined in leetcode-node-scripts.json into the package.json of each exercise directory using the add-scripts.sh bash script.

Injecting Scripts Automatically

1. Ensure you have a package.json file in your exercise directory (create one with npm init -y if necessary).
2. Use the add-scripts.sh script to inject the scripts from leetcode-node-scripts.json into your package.json:

# Execute from the repository root
$ ./add-scripts.sh <path-to-exercise>/package.json

After running the script, your package.json will include the following scripts from leetcode-node-scripts.json:

{
  "start": "node index.js",
  "debug": "node --inspect-brk index.js",
  "test": "node test.js"
}

Understanding the Scripts

• start: Runs the index.js file to start the program. Use this when you want to run you solution.
• debug: Starts the program in debug mode with --inspect-brk, allowing you to attach a debugger and step through the code.
• test: Runs the test.js file to execute all test cases associated with the exercise, ensuring your solution meets the specified requirements.
