2. Assignment-Specific Chat

Assignment Discussion Threads

{
  "assignmentChat": {
    "assignmentId": "hw-003",
    "title": "Binary Search Trees - Q&A",
    "participants": ["instructor", "tas", "students"],
    "threads": [
      {
        "id": "thread-001",
        "topic": "Understanding tree rotation",
        "messages": 15,
        "participants": 8,
        "status": "active"
      },
      {
        "id": "thread-002", 
        "topic": "Test case clarification",
        "messages": 6,
        "participants": 3,
        "status": "resolved"
      }
    ]
  }
}

Code Sharing and Review

# Example: Student asking for help with code
def insert_node(self, root, value):
    if root is None:
        return TreeNode(value)
    
    if value < root.val:
        root.left = self.insert_node(root.left, value)
    elif value > root.val:
        root.right = self.insert_node(root.right, value)
    
    return root

# Question: Is this the correct implementation for BST insertion?
# Getting stack overflow for large inputs 🤔
# TA Response with explanation
def insert_node(self, root, value):
    if root is None:
        return TreeNode(value)
    
    if value < root.val:
        root.left = self.insert_node(root.left, value)
    elif value > root.val:
        root.right = self.insert_node(root.right, value)
    # Add this line to handle duplicates:
    # else:
    #     return root  # Don't insert duplicates
    
    return root

# Your implementation looks correct! The stack overflow might be due to 
# unbalanced input. Try implementing a balanced BST like AVL tree for 
# better performance with large datasets.

3. Direct Messaging

One-on-One Communication

interface DirectMessage {
  chatId: string;
  participants: [UserId, UserId];
  messages: Message[];
  settings: {
    notifications: boolean;
    encryption: boolean;
    messageRetention: '30days' | '1year' | 'forever';
  };
}

Features

  • Private Conversations: Secure one-on-one messaging
  • File Sharing: Share documents, code files, and images
  • Message History: Persistent message storage
  • Status Indicators: Online/offline status and typing indicators

4. Collaboration Session Chat

Real-time Session Communication

interface CollaborationChat {
  sessionId: string;
  participants: SessionParticipant[];
  features: {
    voiceChat: boolean;
    screenShare: boolean;
    codePointing: boolean;  // Point to specific code lines
    sessionRecording: boolean;
  };
}

Integration with Code Editing

# Chat message linked to specific code line
class CodeDiscussion:
    def __init__(self, file_path, line_number, message):
        self.file_path = file_path
        self.line_number = line_number
        self.message = message
        self.timestamp = datetime.now()
        
    def create_annotation(self):
        return {
            'type': 'code_comment',
            'location': f'{self.file_path}:{self.line_number}',
            'content': self.message,
            'author': self.get_current_user()
        }

# Example usage in chat:
# "Line 25 in algorithm.py - shouldn't this be <= instead of <? 🤔"
# Creates clickable link that jumps to the specific line

Code Snippets

Can someone help with this error?

```python
def binary_search(arr, target):
    left, right = 0, len(arr) - 1
    
    while left <= right:
        mid = (left + right) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    
    return -1

Getting IndexError on line 6. Array is [1, 3, 5, 7, 9] and target is 7.


#### Mathematical Expressions
```markdown
The time complexity of this algorithm is **O(log n)**.

For a balanced binary search tree:
- Search: $$T(n) = O(\log n)$$
- Insert: $$T(n) = O(\log n)$$  
- Delete: $$T(n) = O(\log n)$$

But for an unbalanced tree (worst case):
$$T(n) = O(n)$$

            'helpful_resources': self.find_relevant_resources(errors)
        }

Smart Suggestions

**AI Assistant** detected you're asking about binary search implementation:

**Common Issues:**
1. ✅ **Boundary conditions**: Check `left <= right` vs `left < right`
2. ✅ **Integer overflow**: Use `left + (right - left) // 2` instead of `(left + right) // 2`
3. ✅ **Array indexing**: Ensure array is 0-indexed
