ou are given a data structure of employee information, which includes the employee’s unique id, his importance value and his direct subordinates’ id.
For example, employee 1 is the leader of employee 2, and employee 2 is the leader of employee 3. They have importance value 15, 10 and 5, respectively. Then employee 1 has a data structure like [1, 15, ], and employee 2 has [2, 10, ], and employee 3 has [3, 5, ]. Note that although employee 3 is also a subordinate of employee 1, the relationship is not direct.
Now given the employee information of a company, and an employee id, you need to return the total importance value of this employee and all his subordinates.
Employee1has importance value5,andhe has two direct subordinates:employee2andemployee3.They both have importance value3.
So the total importance value of employee1is5+3+3=11.
One employee has at most one direct leader and may have several subordinates.
The maximum number of employees won’t exceed 2000.
