1882. Process Tasks Using Servers

Leetcode Solutions

Two Priority Queues Approach

  1. Initialize two priority queues: availableServers and busyServers.
  2. Populate availableServers with all servers, each represented as a tuple (weight, index).
  3. Iterate over each task in tasks, with the current second t starting from 0.
  4. Move any servers from busyServers to availableServers if they have finished their tasks by the current second t.
  5. If availableServers is not empty, assign the current task to the server at the top of availableServers and move it to busyServers with the updated available time.
  6. If availableServers is empty, take the server at the top of busyServers, assign the current task to it, and update its available time.
  7. Increment t by 1 after each task assignment.
  8. Continue this process until all tasks have been assigned.
  9. Return the list of server indices that correspond to the assigned tasks.
