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.
\n\n\n
Example 1:
\n![](\"https://assets.leetcode.com/uploads/2022/06/20/image-20220620195403-1.png\")
\n\nInput: edges = [1,0,0,0,0,7,7,5]\nOutput: 7\nExplanation:\n- 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.\n- The node 0 has an edge pointing to node 1. The edge score of node 1 is 0.\n- The node 7 has an edge pointing to node 5. The edge score of node 5 is 7.\n- The nodes 5 and 6 have an edge pointing to node 7. The edge score of node 7 is 5 + 6 = 11.\nNode 7 has the highest edge score so return 7.\n\n\n
Example 2:
\n![](\"https://assets.leetcode.com/uploads/2022/06/20/image-20220620200212-3.png\")
\n\nInput: edges = [2,0,0,2]\nOutput: 0\nExplanation:\n- The nodes 1 and 2 have an edge pointing to node 0. The edge score of node 0 is 1 + 2 = 3.\n- The nodes 0 and 3 have an edge pointing to node 2. The edge score of node 2 is 0 + 3 = 3.\nNodes 0 and 2 both have an edge score of 3. Since node 0 has a smaller index, we return 0.\n\n\n

Constraints:
\n\nn == edges.length2 <= n <= 1050 <= edges[i] < nedges[i] != i给你一个有向图，图中有 n 个节点，节点编号从 0 到 n - 1 ，其中每个节点都 恰有一条 出边。
图由一个下标从 0 开始、长度为 n 的整数数组 edges 表示，其中 edges[i] 表示存在一条从节点 i 到节点 edges[i] 的 有向 边。
节点 i 的 边积分 定义为：所有存在一条指向节点 i 的边的节点的 编号 总和。
返回 边积分 最高的节点。如果多个节点的 边积分 相同，返回编号 最小 的那个。
\n\n\n\n
示例 1：
\n\n输入：edges = [1,0,0,0,0,7,7,5]\n输出：7\n解释：\n- 节点 1、2、3 和 4 都有指向节点 0 的边，节点 0 的边积分等于 1 + 2 + 3 + 4 = 10 。\n- 节点 0 有一条指向节点 1 的边，节点 1 的边积分等于 0 。\n- 节点 7 有一条指向节点 5 的边，节点 5 的边积分等于 7 。\n- 节点 5 和 6 都有指向节点 7 的边，节点 7 的边积分等于 5 + 6 = 11 。\n节点 7 的边积分最高，所以返回 7 。\n\n\n
示例 2：
\n\n输入：edges = [2,0,0,2]\n输出：0\n解释：\n- 节点 1 和 2 都有指向节点 0 的边，节点 0 的边积分等于 1 + 2 = 3 。\n- 节点 0 和 3 都有指向节点 2 的边，节点 2 的边积分等于 0 + 3 = 3 。\n节点 0 和 2 的边积分都是 3 。由于节点 0 的编号更小，返回 0 。\n\n\n
