**Input Format**

The first line contains a single integer, N . The next N lines denote the matrix’s rows, with each line containing N space-separated integers describing the columns.

**Output Format**

Print the absolute difference between the two sums of the matrix’s diagonals as a single integer.

**Sample Input**

```
3
11 2 4
4 5 6
10 8 -12
```

**Sample Output**

```
15
```

**Explanation**

The primary diagonal is:

```
11
5
-12
```

Sum across the primary diagonal: 11 + 5 – 12 = 4

The secondary diagonal is:

```
5
4
10
```

Sum across the secondary diagonal: 4 + 5 + 10 = 19

Difference: |4 – 19| = 15

Here is the solution
