Составление программы на алгоритмическом языке, выполняющей указанные преобразования с матрицами

Задание №37

Расположить в матрице A(N,N) элементы в последовательности указанной на рисунке.

Требования к программе:

1. Составить программу на алгоритмическом языке, выполняющую указанные преобразования с матрицами;

2. Вывести вектор, полученный случайно;

3. Вывести преобразованную матрицу с новым содержимым вектора;

4. Программа должна строиться таким образом, чтобы существовала возможность её использования с массивами любой размерности, содержащими произвольные элементы;

5. В программе должна быть предусмотрена выдача на печать исходных и преобразованных матриц;

6. Полученные результаты должны быть занесены в файл последовательного доступа и доступны для просмотра из него.
