582. Kill Process

Leetcode Solutions

Approach # HashMap + Depth First Search

  1. Initialize a HashMap processTree to store the parent-child relationship.
  2. Iterate over the ppid array to populate the processTree with the corresponding pid as children.
  3. Define a recursive function killAllChildren that takes a process ID and a list to collect the processes to be killed.
  4. Add the current process ID to the list of processes to be killed.
  5. Check if the current process ID has children in the processTree.
  6. If it has children, recursively call killAllChildren for each child process ID.
  7. Call killAllChildren starting with the kill process ID and an empty list.
  8. Return the list of processes to be killed.
