PROGRAMMING:The sum of some elements of matrix

Program input integer n (1 < n < 10), and then input n * n integers (n-order matrix) in order to store in a two-dimensional array of N rows and N columns. It is required to output the sum of the upper triangular elements and the lower triangular elements of the matrix (the main diagonal belongs to the common elements of the upper and lower triangles).
###Input example:
```in
three
1 2 3
4 5 6
7 8 9
```
###Output example:
```out
26 34
```
