Input & Output
Example 1 — Mixed Weekend and Working Day Submissions
Input Table:
| task_id | assignee_id | submit_date |

| 1 | 1 | 2022-06-04 |

💡 Note:
Task 1 submitted on 2022-06-04 (Saturday), Task 2 on 2022-06-06 (Monday), and Task 3 on 2022-06-05 (Sunday). So we have 2 weekend submissions and 1 working day submission.
