Implementing Pathfinding

Use the accumulated data to calculate the best path from one station to another. Implement algorithms to find the shortest path, fastest route, or fewest transfers based on user preferences.

Final Steps

After creating the QCards, follow these steps to finalize your metro app:

• 1. Go to `/user/Relationship` and update the connections. If the data in `categories[0]` and `categories[1]` is provided correctly, the app will automatically detect relationships and update them.

• 2. Go to `/apps` and press the 'Create App' button. Fill out the form as you want, except the 'Type' field, which should be selected as 'stations'. Press the 'Create App' button.

• 3. Your app will be created and listed on the `/apps` page. Go to the newly created app, and in the app menu, select the 'Add Card' item. A page will pop up. Check the 'Include Children' box and select the grandparent card (e.g., 'London Metro'). It will automatically fetch all QCards and add them to your app.

• 4. Your app is now ready! Users can add their ads to your app. After 100 ads are added, your app will be monetized, and you will receive around 20% of the ad revenue in your wallet.
