key_takeaways:
- "**Null markers are essential**: They encode the tree's *structure*, not just its values — this is what distinguishes serialization from simple traversal"
- "**Preorder + nulls = unique tree**: Preorder traversal with null markers uniquely identifies any binary tree, enabling perfect reconstruction"
- "**BFS matches intuition**: Level-order serialization is often easier to visualize and debug since it matches how we draw trees"
- "**BFS matches intuition**: Level-order serialization is often easier to visualise and debug since it matches how we draw trees"
- "**This pattern appears everywhere**: Serialization concepts apply to JSON parsing, protocol buffers, database storage, and network transmission of complex data structures"
time_complexity: "O(n). Both serialization and deserialization visit each node exactly once, where `n` is the number of nodes in the tree."
