Understanding the Node With Highest Edge Score Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a directed graph with n nodes labeled from 0 to n - 1, where each node has exactly one outgoing edge. The graph is represented by a given 0-indexed integer array edges of length n, where edges[i] indicates that there is a directed edge from node i to node edges[i]. The edge score of a node i is defined as the sum of the labels of all the nodes that have an edge pointing to i. Return the node with the highest edge score. If multiple nodes have the same edge score, return the node with the smallest index.

How Interview Coder Helps
Get real-time assistance for Node With Highest Edge Score problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
edges = [1,0,0,0,0,7,7,5]7- The nodes 1, 2, 3 and 4 have an edge pointing to node 0. The edge score of node 0 is 1 + 2 + 3 + 4 = 10. - The node 0 has an edge pointing to node 1. The edge score of node 1 is 0. - The node 7 has an edge pointing to node 5. The edge score of node 5 is 7. - The nodes 5 and 6 have an edge pointing to node 7. The edge score of node 7 is 5 + 6 = 11. Node 7 has the highest edge score so return 7.
edges = [2,0,0,2]0- The nodes 1 and 2 have an edge pointing to node 0. The edge score of node 0 is 1 + 2 = 3. - The nodes 0 and 3 have an edge pointing to node 2. The edge score of node 2 is 0 + 3 = 3. Nodes 0 and 2 both have an edge score of 3. Since node 0 has a smaller index, we return 0.
