# MultiDimensional Arrays

Problem Description

A multidimensional array is an array of arrays. Each element of a multidimensional array is an array itself. For example,

```int[][] arr = new int[3][4];
```

Here, we have created a multidimensional array named arr. It is a 2-dimensional array, that can hold a maximum of 12 elements,

Remember, Java uses zero-based indexing, that is, indexing of arrays in Java starts with 0 and not 1.

Let's take another example of the multidimensional array. This time we will be creating a 3-dimensional array.

For example:

```String[][][] names = new String[3][4][2];
```

Here, data is a 3d array that can hold a maximum of 24 (3 * 4 * 2) elements of type String.

Take 2D matrix A of size N X M as an input and print M integers denoting the column-wise sum of each of the M columns.

Problem Constraints

1 <= N, M <= 103

1 <= A[i][j] <= 100

Input Format

First line contains two space-separated integers N and M.

Each of the next N lines contains M space-separated integers denoting the matrix elements.

Output Format

Print M space-separated integers where each denoting the column-wisw sum of A.

Example Input

Input 1:

``` 3 4
3 2 1 3
1 2 3 4
4 3 1 2```

Example Output

Output 1:

``` 8 7 5 9
```

Example Explanation

Explanation 1:

``` Sum of elements of first column : 3 + 1 + 4 = 8
Sum of elements of second column : 2 + 2 + 3 = 7
Sum of elements of third column : 1 + 3 + 1 = 5
Sum of elements of fourth column : 3 + 4 + 2 = 9```
