Basic of programming

{0.3 points} Task 1:

To do: Three integers are entered (they should be in the range from 0 to 10). Find the maximum (the greatest) number among the three entered numbers. Check entered values using assert function.

Expected output:

please enter three integer numbers
>>> 6   >>> 1   >>> 9
The maximum number is 9 
please enter three integer numbers
>>> 1   >>> 2   >>> 13
Incorrect input! must be in the range from 0 to 10

{0.3 points} Task 2:

To do: Two real numbers are given. Find a maximum (the greatest) and minimum (the least) number among them. Output max and min.

Expected output:

please enter three integer numbers
>>> 3.0    >>> 55.5   
Maximum number: 55.5  Minimum number: 3.0 

{0.5 points} Task 3:

To do: A two-digit number is given. Find the minimum and the maximum among its digits and swap the digits in the number. Check entered values using assert function (it should be two-digit number).

Expected output:

please enter two-digit number
>>> 74    
max = 7, min = 4, swapped = 47
please enter two-digit number
>>> 7    
Incorrect input! should be two-digit number

{1 point} Task 4:

To do: The integers A, B and k are given. At first output the larger of A and B, then the lesser of them. Print True if the difference between the numbers does not exceed the value of k and print False otherwise. Check the correctness of your program with at least three input data sets, give the log of the program in the form of a comment.

Expected output:

Please enter three integer numbers
>>> 3   >>> 5    >>> 2
5 3 True 
Please enter three integer numbers
>>> 44   >>> 20   >>> 9
44 20 False 

{1 point} Task 5:

To do: A three-digit integer is given. Find the maximum (the greatest) digit and minimum (the least) digit among the three digits of the given number and swap them. Output the numbers. Check entered values using assert function (it should be three-digit number).

Expected output:

please enter three-digit integer 
>>> 167
After swaping maximum and minimum we have: 761
please enter three-digit integer 
>>> 7    
Incorrect input! should be three-digit number

{0.4 points} Task 6:

To do: For a given real x find the value of the following function f.

Expected output:

please enter a real number
>>> -4
The result of function f is 4
---
please enter a real number
>>> 1.5
The result of function f is 2.25

{0.3 points} Task 7:

To do: An integer is given. Use random function to generate this number. Display its description in the following form: “negative even number” or “negative odd number” or “zero number” or “positive odd number” or “positive even number”. Check the correctness of your program, provide a log of the program in the form of a comment.

Expected output:

generated number:
-4
negative even number
---
generated number:
-3
negative odd number 

{0.4 points} Task 8:

To do: The numbers X and Y are given. Print True if the point with coordinates (X, Y) lies in the fourth coordinate quarter and print False otherwise. Do not use conditional if statement.

Expected output:

Please enter the values of x and y
>>> 8   >>> -4
True
---
Please enter the values of x and y
>>> -9  >>> 3
False 

{0.4 points} Task 9:

To do: The coordinates X and Y of the chessboard field are given (integers lying in the range of 1–8). Use random function to generate these numbers. Considering that the bottom left cell of the board (1, 1) is black, output True if the field of X and Y is white and print False otherwise.

Expected output:

Please enter the values of x and y between 1 and 8 inclusive
2 7
False 
---
Please enter the values of x and y between 1 and 8 inclusive
3 5
True 

{0.3 points} Task 10:

To do: Three integer numbers are given. Use random function to generate these numbers. Print true if none of these numbers are positive and False otherwise. Check the correctness of your program with at least three input data sets.

Expected output:

generated numbers:
-9 -6 -49
True
---
generated numbers:
0 77 -5
False

{0.3 points} Task 11:

To do: Integers x, y are given. Calculate the value of the function.

A snippet of code:

begin
  var x, y: integer; // arguments of f function
  Write('Input integers x, y: ');
  Readln(x, y);
 
  var f: integer;    // TODO: set the value of the function f(x, y) to f variable 
 
  WritelnFormat('f({0}, {1}) = {2}', x, y, f);
end.

Expected output:

Input integers x, y: 
>>> 7    >>> -5
f (7, -5) =  70
