LeetCode ProblemInsert into a Binary Search Tree
You are given the root node of a binary search tree (BST) and a value to insert into the tree. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Notice that there may exist multiple valid ways for the insertion, as long as the tree remains a BST after insertion. You can return any of them.

Examples
# Example 1
Input
root = [4,2,7,1,3], val = 5
Output
[4,2,7,1,3,5]
# Example 2
Input
root = [40,20,60,10,30,50,70], val = 25
Output
[40,20,60,10,30,50,70,null,null,25]
# Example 3
Input
root = [4,2,7,1,3,null,null,null,null,null,null], val = 5
Output
[4,2,7,1,3,5]
Constraints
The number of nodes in the tree will be in the range [0, 104].
-108 <= Node.val <= 108
All the values Node.val are unique.
-108 <= val <= 108
It's guaranteed that val does not exist in the original BST.

Frequently Asked Questions
Common questions about solving Insert into a Binary Search Tree and using Phantom Code during coding interviews.
How does Phantom Code help me solve coding problems like Insert into a Binary Search Tree during interviews?
Phantom Code generates complete solutions instantly with proper complexity analysis, letting you focus on explaining your approach and demonstrating problem-solving skills rather than getting stuck on implementation details during high-pressure situations.
What if the interviewer asks follow-up questions or modifications to problems like Insert into a Binary Search Tree?
Phantom Code adapts in real-time. Screenshot the modified problem or use audio mode to capture the interviewer's follow-up, and get an updated solution within seconds — including edge cases and optimizations.
Can Phantom Code help me communicate my solution for problems like Insert into a Binary Search Tree?
Yes. Phantom Code provides step-by-step approach explanations with 3 progressive thoughts, so you can walk through your solution naturally. It also provides time and space complexity analysis to discuss trade-offs.
How does Phantom Code assist with different programming languages for Insert into a Binary Search Tree type problems?
Phantom Code supports 11 programming languages including Python, Java, C++, JavaScript, TypeScript, Go, Rust, Ruby, Swift, Kotlin, and C#. Set your preferred language and get idiomatic solutions.
What coding mistakes does Phantom Code help me avoid during Insert into a Binary Search Tree interviews?
Phantom Code catches common mistakes like off-by-one errors, missing edge cases, incorrect base conditions, and suboptimal approaches. It provides clean, well-structured code that handles all edge cases.
Is Phantom Code detectable when solving problems like Insert into a Binary Search Tree during live interviews?
No. Phantom Code runs as an invisible desktop overlay that doesn't appear in screen shares, recordings, or proctoring software. It works with Zoom, HackerRank, CodeSignal, CoderPad, and all major platforms.
How does Phantom Code help when I'm struggling with Insert into a Binary Search Tree style questions under pressure?
The AI provides structured guidance: first the approach (what algorithm/data structure to use and why), then the implementation with clean code, and finally complexity analysis. This helps you think clearly even under pressure.
Does Phantom Code work for the coding platforms used in Insert into a Binary Search Tree interviews?
Yes. Phantom Code works with all major coding platforms including LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, and any browser-based coding environment.
