LeetCode ProblemConstruct 2D Grid Matching Graph Layout
You are given a 2D integer array edges representing an undirected graph having n nodes, where edges[i] = [ui, vi] denotes an edge between nodes ui and vi. Construct a 2D grid that satisfies these conditions: It is guaranteed that edges can form a 2D grid that satisfies the conditions. Return a 2D integer array satisfying the conditions above. If there are multiple solutions, return any of them.

Examples
# Example 1
Input
n = 4, edges = [[0,1],[0,2],[1,3],[2,3]]
Output
[[3,1],[2,0]]
# Example 2
Input
n = 5, edges = [[0,1],[1,3],[2,3],[2,4]]
Output
[[4,2,3,1,0]]
# Example 3
Input
n = 9, edges = [[0,1],[0,4],[0,5],[1,7],[2,3],[2,4],[2,5],[3,6],[4,6],[4,7],[6,8],[7,8]]
Output
[[8,6,3],[7,4,2],[1,0,5]]
Constraints
2 <= n <= 5 * 104
1 <= edges.length <= 105
edges[i] = [ui, vi]
0 <= ui < vi < n
All the edges are distinct.
The input is generated such that edges can form a 2D grid that satisfies the conditions.

Frequently Asked Questions
Common questions about solving Construct 2D Grid Matching Graph Layout and using Phantom Code during coding interviews.
How does Phantom Code help me solve coding problems like Construct 2D Grid Matching Graph Layout 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 Construct 2D Grid Matching Graph Layout?
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 Construct 2D Grid Matching Graph Layout?
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 Construct 2D Grid Matching Graph Layout 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 Construct 2D Grid Matching Graph Layout 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 Construct 2D Grid Matching Graph Layout 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 Construct 2D Grid Matching Graph Layout 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 Construct 2D Grid Matching Graph Layout interviews?
Yes. Phantom Code works with all major coding platforms including LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, and any browser-based coding environment.
