K-th Employee Receiving Data

K-th Employee Receiving Data Employees form a rooted tree. The array boss describes reporting relationships: boss[i] is the direct manager of employee i. The Boss has value -1 in boss. Employee IDs range from 0 to n - 1. When an employee receives data, that employee receives it first, then sends it to direct reports in ascending employee-ID order. Each report recursively follows the same rule. For each query [startNode, k], return the ID of the k-th employee receiving data when transmission starts at startNode. startNode itself is the first receiver. Return -1 if its subtree contains fewer than k employees. Example Input 6 3 -1 0 0 1 1 2 0 1 1 3 0 6 Output 0 4 5
