ASSESSMENT: One-time cross-numbering of tasks Examination by a specialist, which are tasks of the second level and are sub-tasks of the Medical Card

We are faced with a difficult task that needs to be solved. [file]23213[/file] This should be done once. [file]23213[/file] The task is as follows: [file]23213[/file] 1. There is an array of data. [file]23213[/file] 2. There are two types of problems in the array: [file]23213[/file] - The patient's medical card is a first-level task [file]23213[/file] - Examination by a specialist is a second-level task and is a subtask of the Medical Card [file]23213[/file] 3. In the Medical Cards and Examinations, there is a Patient who is identified by Surname, First Name, Patronymic. [file]23213[/file] 4. Sub-tasks for Examination by a specialist have additional data, according to which they must be numbered from 1 to N, where N is the total number of such sub-tasks: [file]23213[/file] 5. For the end-to-end numbering of tasks of the Examination by a specialist, we can rely on and take into account: [file]23213[/file] - Name of the Patient [file]23213[/file] - ID of the subtask for examination by a specialist [file]23213[/file] - The date of the actual examination for this subtask [file]23213[/file] Example as it is now: [file]23213[/file] 1. There is a task Medical card for Ivanov Sergey Petrovych [file]23213[/file] The Medical Card has four subtasks for examination by a specialist, where Ivanov Serhiy Petrovych acts as a patient: [file]23213[/file] - the first: id - 45, date of actual examination - 01.11.2024 [file]23213[/file] - second: id - 48, date of actual examination - 01.11.2024 [file]23213[/file] - third: id - 108, date of actual examination - 11/12/2024 [file]23213[/file] - fourth: id - 211, date of actual examination - 20.11.2024 [file]23213[/file] 2. There is a task Medical card for Kotenko Maria Oleksiivna [file]23213[/file] She has three subtasks for examination by a specialist, where Kotenko Maria Oleksiivna acts as a patient: [file]23213[/file] - the first: id - 109, date of actual examination - 12,11,2024 [file]23213[/file] - second: id - 224, date of actual examination - November 20, 2024 [file]23213[/file] - the third: id - 348, date of actual examination - November 30, 2024 [file]23213[/file] 3. There is a task Medical card for Mykhailo Ihorovych Korotkov [file]23213[/file] She has five subtasks for examination by a specialist, where Mykhailo Igorovich Korotkov acts as a patient: [file]23213[/file] - the first: id - 12, date of actual examination - October 28, 2024 [file]23213[/file] - second: id - 54, date of actual examination - 01.11.2024 [file]23213[/file] - third: id - 304, date of actual examination - 10,12,2024 [file]23213[/file] - fourth: id - 308, date of actual examination - 10,12,2024 [file]23213[/file] - fifth: id - 309, date of actual examination - 10.12.2024 [file]23213[/file] After performing the end-to-end numbering action, we should get the numbering for the subtasks in the example: [file]23213[/file] 1 for — the first: id - 45, date of actual examination - 01.11.2024 [file]23213[/file] 2 for the second: id - 48, date of actual examination - 01.11.2024 [file]23213[/file] 3 for — the third: id - 108, date of actual examination - 11/12/2024 [file]23213[/file] 4 for — the fourth: id - 211, date of actual examination - 20.11.2024 [file]23213[/file] 1 for — the first: id - 109, date of actual examination - 12,11,2024 [file]23213[/file] 2 for the second: id - 224, date of actual examination - 20.11.2024 [file]23213[/file] 3 for — the third: id - 348, date of actual examination - 30.11.2024 [file]23213[/file] 1 for — the first: id - 12, date of actual examination - 28.10.2024 [file]23213[/file] 2 for the second: id - 54, date of actual examination - 01.11.2024 [file]23213[/file] 3 for — the third: id - 304, date of actual examination - 10.12.2024 [file]23213[/file] 4 for — the fourth: id - 308, date of actual examination - 10.12.2024 [file]23213[/file] 5 for — fifth: id - 309, date of actual examination - 10.12.2024 [file]23213[/file] In fact, we have in the data array: [file]23213[/file] - 1,479 problems Medical card with unique patients.
