Right Answer:

Input: arr = [3, 5, 2, 3, 5, 3, 2], num1 = 3, num2 = 2
Output: 1
(Closest 3 and 2 are at indices 3 and 4 or 5 and 6)

✅ Efficient Solution (O(n) time, O(1) space):

You only need a single pass through the array.

🧠 Idea:

• Track last seen positions of num1 and num2

• Update minimum distance when both have been seen

✅ Python Code:

def min_distance(arr, num1, num2):
min_dist = float(‘inf’)
last_pos1 = last_pos2 = -1

A web server handles an HTTP request by following these steps:

1. **Receive Request**: The server listens for incoming HTTP requests on a specific port (usually port 80 for HTTP or port 443 for HTTPS).
2. **Parse Request**: It parses the request to extract the method (GET, POST, etc.), URL, headers, and body.
3. **Process Request**: The server determines how to respond based on the request. This may involve retrieving files, querying a database, or executing server-side scripts.
4. **Generate Response**: It creates an HTTP response, which includes a status code (like 200 for success), headers, and the requested content (like HTML, JSON, etc.).
5. **Send Response**: The server sends the response back to the client (usually a web browser) over the network.
6. **Log Request**: Optionally, the server logs the request details for monitoring and analysis.
