12 | | -<p>1 Task: <br/><pre> |
13 | | - 1. Hello world |
14 | | - 2. Accept the username as a program argument.Say hello to the user using string formatting. |
15 | | -    Ask what language is the user's favorite, in case it is ruby, answer that the user is |
16 | | -     a sucker, otherwise be sure to answer that soon it will be ruby and put |
17 | | -      different comments for several languages. |
18 | | - 3. Ask user enter ruby language command and OS command. Execute ruby and OS command</pre> |
19 | | -</p> |
20 | | -<p> 2 Task:<br/><pre> |
21 | | - 1. Find the sum of prime divisors of a number. |
22 | | - 2. Find the number of odd digits of a number greater than 3 |
23 | | - 3. Find the multiple of such divisors of a number, the sum of the digits less than |
24 | | -    the sum of the digits of the original number. |
25 | | -</pre></p> |
26 | | -<p> 3 Task:<br/><pre> |
27 | | - 1. Write methods that find the minimum, elements, number of the first positive element. |
28 | | -     Each operation in a separate method. Solve the problem using loops (for and while) |
29 | | - 2. Write a program that takes two values as an argument. The first |
30 | | -    value tells which of the methods of task 1 to execute, the second one |
31 | | -      tells where to read the list from where the file address should be written |
32 | | -        as an argument. Next, you need to read the array and execute the method. |
33 | | -</pre></p> |
34 | | -<p> 4 Task:<br/><pre> |
35 | | - 1. Given an integer array. It is necessary to find the number of emails located after |
36 | | -  the last max |
37 | | - 2. Given an integer array. It is necessary to place the elements, located |
38 | | -    before the min, at the end of the array |
39 | | - 3. An integer array and an interval (a,b) are given. Need to find the max of the elements |
40 | | -    in this interval |
41 | | - 4. Given an integer array. Output indexes of el-in, which are less than its left |
42 | | -    neighbor, and the number of such numbers |
43 | | - 5. For the given list + numbers, construct a list of all + prime divisors |
44 | | -    of the e-list without repetitions |

48 | | -<div> |
49 | | -<p><h4>1Ex Object and clesses:</h4> <br/><pre> |
50 | | - 1. Create the Student class in a separate file with the object fields ID, Last Name, |
51 | | -  First Name, Middle Name, Phone, Telegram, Mail, Git. Full name is required, others are not. |
52 | | -   Write a constructor, write a getter and a setter for each field, |
53 | | -    when naming methods it is MANDATORY to use ruby naming conventions. |
54 | | - 2. Create several objects from a separate main.rb file and display information about them |
55 | | -  on the screen. Think over the correct way to display information about the current state of |
56 | | -   the object on the screen, modify the class. |
57 | | - 3. Avoid code duplication in constructor, getter and setter. |
58 | | - 4. Use attributes to concisely write getters and setters. |
59 | | - 5. Provide in the constructor the ability to create objects with any combination of |
60 | | -   filling in optional fields. |
61 | | - 6. Add a CLASS method that checks if some string is a phone number. Modify the class |
62 | | -  so that at an arbitrary point in time there could not be an object with an invalid |
63 | | -   string in the phone number field, for this you will have to modify the constructors. |
64 | | -    Test the resulting class. |
65 | | - 7. Create validations for the correct form of the string in the remaining fields. |
66 | | - 8. Write a validate method that performs two validations of the presence of the |
67 | | -   git and the presence of any contact for communication, if possible separate the methods. |
68 | | - 9.Write a set_contacts method that sets the value of a field or fields for the entered contacts. |
69 | | - 10. Start building a class diagram by describing this class.</pre> |

71 | | -<p><h4>2Ex Reading, view, record entity:</h4> <br/><pre> |
72 | | - 1. Think about the structure of String representation of the class object,coordinate it |
73 | | -  with clause 2. Write a separate constructor accepting a string as an input, |
74 | | -   which parses this parses the string and calls the standard constructor with |
75 | | -    arses this string and calls the standard constructor with the parameters. |
76 | | -     Test the constructor from the main class. |
77 | | - 2. Design an exception structure for the given constructor |
78 | | -  constructor in case parsing of the string is impossible and in case the data in the |
79 | | -   string didn't pass validation. if the data in the string is not validated. 3. |
80 | | - 3. Write a getInfo method that returns brief |
81 | | -  information about the student - Surname and Initials; git, communication |
82 | | -   (specify any means of communication and state what it is) on ONE line. If possible, |
83 | | -    divide the method into components (in the future this information will be displayed in |
84 | | -     table and you will have to take it in parts). |
85 | | - 4. Write Student_short class that has 4 ID fields, |
86 | | -  Surname and initials, Git, Contact. The fields can't be edit. There are two possible |
87 | | -   constructors - one of them is an object of class Student.Student class object, the other |
88 | | -    has an ID and a string that contains and a string that contains all other information. |
89 | | - 5. Refactoring by separating the superclass and removing code duplication in the Student |
90 | | -  and Student_short classes. |
91 | | - 6. Mark the changes in the class diagram. |
92 | | - 7. Write a read_from_txt method that receives file address arguments, throws an exception with |
93 | | -  notification if the address is invalid, and returns an array of Student type objects. |
94 | | - 8. Test the method by outputting a brief output of information about each object. |
95 | | - 9. Write a write_to_txt method that receives as address, name of a file, and a list of objects |
96 | | -  of type Student. |
97 | | - 10. Test the compatibility of these methods. |
