Depth-First Search (DFS) Approach

  1. Create an adjacency list adjList to represent the tree structure of the company.
  2. Iterate over the manager array and for each employee i, add an edge from manager[i] to i in adjList.
  3. Define a recursive DFS function that takes the current node and the accumulated inform time. a. Update the maxTime with the maximum of maxTime and the accumulated inform time. b. Recursively call DFS for all subordinates of the current node, adding the current node's inform time to the accumulated time.
  4. Call the DFS function starting from headID with an initial time of 0.
  5. Return the maxTime after the DFS traversal is complete.
