Với một ma trận vuông, nhiệm vụ là chúng ta xoay nó bằng 180 độ theo hướng ngược chiều kim đồng hồ mà không sử dụng bất kỳ không gian bổ sung nào. & NBSP;

Ví dụ: & nbsp; 

Input :  1  2  3
         4  5  6
         7  8  9
Output : 9 8 7 
         6 5 4 
         3 2 1

Input :  1 2 3 4 
         5 6 7 8 
         9 0 1 2 
         3 4 5 6 
Output : 6 5 4 3 
         2 1 0 9 
         8 7 6 5 
         4 3 2 1

Phương pháp: 1 (chỉ in ma trận xoay) & nbsp; Giải pháp của vấn đề này là xoay ma trận bằng 180 độ, chúng ta có thể dễ dàng theo bước đó & nbsp; 
The solution of this problem is that to rotate a matrix by 180 degrees we can easily follow that step 

Matrix =  a00 a01 a02
          a10 a11 a12
          a20 a21 a22

when we rotate it by 90 degree
then matrix is
Matrix = a02 a12 a22
         a01 a11 a21
         a00 a10 a20
  
when we rotate it by again 90 
degree then matrix is 
Matrix = a22 a21 a20
         a12 a11 a10
         a02 a01 a00

Từ hình minh họa ở trên, chúng ta có được điều đó chỉ đơn giản là xoay ma trận bằng 180 độ thì chúng ta sẽ phải in ma trận theo cách thức., we get that simply to rotate the matrix by 180 degrees then we will have to print the given matrix in a reverse manner.

Let the given matrix be

13 14 15 16

First we find transpose.
1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 16

Then we reverse elements of every column.
4 8 12 16

then transpose again

Let the given matrix be

First we find transpose.

Then we reverse elements of every column.

then transpose again

Auxiliary Space : O(1)
In the code above, the transpose of the matrix has to be found twice, and also, columns have to be reversed twice. 
So, we can have a better solution.

Here, we swap the values in the respective positions.

Let the given matrix be
1  2  3  4
5  6  7  8
9  10 11 12
13 14 15 16

First we find transpose.
1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 16

Then we reverse elements of every column.
4 8 12 16

then transpose again
