Question

задания по паскалюДаны координаты двух различных полей шахматной доски х1, y1, x2, y2 (целые числа, лежащие в диапазоне 1-8). Проверить истинность высказывания: «Данные поля имеют одинаковый цвет».помагите решить

Answer 1

var
x1,y1,x2,y2:integer;
begin
readln(x1);
readln(y1);
readln(x2);
readln(y2);
if (x1+y1+x2+y2) mod 2 = 0 then
writeln('ONI IMEUT ODINAKOVIJ ZVET');
else
writeln('ONI IMEUT RAZNIJ ZVET');
end.

Task Analysis

To solve the given problem, we need to check whether two different chessboard squares have the same color. The squares are represented by their coordinates (x1, y1) and (x2, y2), where the coordinates are integers in the range of 1-8.

Solution

To determine if the given fields have the same color, we can use the property of a chessboard where squares of the same color have either both even or both odd sums of their coordinates.

We can calculate the sum of the coordinates for each field and then compare the parity of the sums to determine if the fields have the same color.

Let's proceed with the solution.

Code Solution

Here's a Python function to check if the given fields have the same color:

def same_color(x1, y1, x2, y2):
    return (x1 + y1) % 2 == (x2 + y2) % 2

You can use this function by passing the coordinates of the two fields (x1, y1, x2, y2) as arguments. If the function returns True, it means the fields have the same color; otherwise, they have different colors.

Example

For example, if we have fields with coordinates (1, 1) and (2, 3), we can use the function `same_color(1, 1, 2, 3)` to check if they have the same color.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
