Technical Questions

  1. Task Management System (Data Structures, Set, Map)
    Design a Task Management System supporting the following operations:

    • assign_user(task_id, user_id): Assign a user to a specific task. Return the list of users currently assigned to the task.
    • remove_user(task_id, user_id): Remove a user from a specific task. Return ‘User not assigned to task’ if the user is not assigned.
    • get_task_count(): Return the total number of tasks in the system.

    Test Cases:

    • assign_user(1, 'Alice') - returns ‘Alice’
    • assign_user(1, 'Bob') - returns ‘Alice’, ‘Bob’
    • remove_user(1, 'Charlie') - returns ‘User not assigned to task’
    • get_task_count() - returns 1

    Data Scale: Assume the number of tasks does not exceed 1000, and the number of users does not exceed 100000.

Tips & Insights

Focus on understanding data structures and their applications in real-world scenarios. Practice implementing classes and methods that handle various operations efficiently.
