Question

Впрограмме описан одномерный целочисленный массив с индексами от 1 до 5. в фрагменте программы массив сначала заполняется, а потом изменяется. чему будут равны элементы этого массива? в ответе перечислите их через запятую.
​
for i: =5 downto 1 do a[i]: =4+i;
for i: =2 to 6 do begin
k: = a[i-1];
a[6-i]: =2*k;
end;
