LeetCode Problem

Maximum Score of a Node Sequence

There is an undirected graph with n nodes, numbered from 0 to n - 1. You are given a 0-indexed integer array scores of length n where scores[i] denotes the score of node i. You are also given a 2D integer array edges where edges[i] = [ai, bi] denotes that there exists an undirected edge connecting nodes ai and bi. A node sequence is valid if it meets the following conditions: The score of a node sequence is defined as the sum of the scores of the nodes in the sequence. Return the maximum score of a valid node sequence with a length of 4. If no such sequence exists, return -1.

How Phantom Code Helps

Get real-time assistance for Maximum Score of a Node Sequence problems during coding interviews. Phantom Code provides instant solutions and explanations.

Examples

# Example 1

Input

scores = [5,2,9,8,4], edges = [[0,1],[1,2],[2,3],[0,2],[1,3],[2,4]]

Output

# Example 2

Input

scores = [9,20,6,4,11,12], edges = [[0,3],[5,3],[2,4],[1,3]]

Output

-1

Constraints

n == scores.length

4 <= n <= 5 * 104

1 <= scores[i] <= 108

0 <= edges.length <= 5 * 104

edges[i].length == 2

0 <= ai, bi <= n - 1

ai != bi

There are no duplicate edges.

Frequently Asked Questions

Common questions about solving Maximum Score of a Node Sequence and using Phantom Code during coding interviews.

How does Phantom Code help me solve coding problems like Maximum Score of a Node Sequence 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 Maximum Score of a Node Sequence?

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 Maximum Score of a Node Sequence?

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 Maximum Score of a Node Sequence 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 Maximum Score of a Node Sequence 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 Maximum Score of a Node Sequence 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 Maximum Score of a Node Sequence 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 Maximum Score of a Node Sequence interviews?

Yes. Phantom Code works with all major coding platforms including LeetCode, HackerRank, CodeSignal, CoderPad, HackerEarth, and any browser-based coding environment.
