1082. 员工的重要度

1082. 员工的重要度

中文English

给定一个保存员工信息的数据结构,它包含了员工唯一的id,重要度 和 直系下属的id。

比如,员工1是员工2的领导,员工2是员工3的领导。他们相应的重要度为15, 10, 5。那么员工1的数据结构是[1, 15, [2]],员工2的数据结构是[2, 10, [3]],员工3的数据结构是[3, 5, []]。注意虽然员工3也是员工1的一个下属,但是由于并不是直系下属,因此没有体现在员工1的数据结构中。

现在输入一个公司的所有员工信息,以及单个员工id,返回这个员工和他所有下属的重要度之和。

样例

样例 1:

输入: employees = [[1,2,[2]], [2,3,[]]], id = 2
输出: 3
解释:
员工2的重要度为3。

样例 2:

输入: employees = [[1, 5, [2, 3]], [2, 3, []], [3, 3, []]], id = 1
输出: 11
解释:
员工1自身的重要度是5,他有两个直系下属2和3,而且2和3的重要度均为3。因此员工1的总重要度是 5 + 3 + 3 = 11

注意事项

  • 一个员工最多有一个直系领导,但是可以有多个直系下属
  • 员工数量不超过2000。
输入测试数据 (每行一个参数)如何理解测试数据?
