You have a data structure of employee information, including the employee's unique ID, importance value, and direct subordinates' IDs.

You are given an array of employees `employees` where:

- `employees[i].id` is the ID of the `ith` employee.
- `employees[i].importance` is the importance value of the `ith` employee.
- `employees[i].subordinates` is a list of the IDs of the direct subordinates of the `ith` employee.

Given an integer `id` that represents an employee's ID, return the total importance value of this employee and all their direct and indirect subordinates.

Example 1:

    Input: employees = [[1,5,[2,3]],[2,3,[]],[3,3,[]]], id = 1
    Output: 11
    Explanation: Employee 1 has an importance value of 5 and has two direct subordinates: employee 2 and employee 3.
    They both have an importance value of 3.
    Thus, the total importance value of employee 1 is 5 + 3 + 3 = 11.

Example 2:

    Input: employees = [[1,2,[5]],[5,-3,[]]], id = 5
    Output: -3
    Explanation: Employee 5 has an importance value of -3 and has no direct subordinates.
    Thus, the total importance value of employee 5 is -3.

Constraints:

- `1 <= employees.length <= 2000`
- `1 <= employees[i].id <= 2000`
- All `employees[i].id` are unique.
- `-100 <= employees[i].importance <= 100`
- One employee has at most one direct leader and may have several subordinates.
- The IDs in `employees[i].subordinates` are valid IDs.
