Programma matricas drukāšanai Z formā
Ņemot vērā a kvadrāts pasūtījuma matrica n*n mums ir jādrukā matricas elementi AR formā
Input: [[4 5 6 8] [1 2 3 1] [7 8 9 4] [1 8 7 5]] Output: 4 5 6 8 3 8 1 8 7 5 Input: [[4 5 6 8 5] [1 2 3 1 4] [7 8 9 4 7] [1 8 7 5 2] [7 9 5 6 9] [9 4 5 6 6]] Output: 4 5 6 8 5 1 9 8 7 9 4 5 6 6
Mums jāšķērso matricas pirmā rinda, pēc tam otrā diagonāle un pēc tam pēdējā rinda.
