# Accenture Coding Question | Row wise 2D array Sort | June 2021

Problem Statement: Implement a function

int[][] Sort2DArraysByRow(int m,int n,int arr[][])

The function accepts a two-dimensional integer array ‘arr’ of ‘m’ rows and ‘n’ columns . Implement the function to return 2D array after sorting each row of array ‘arr’ in ascending array.

Assumption:

1. m>0 and n>0

2. Array index starts from (0,0).

Note: You need to sort each row in ascending order.

Example:

Input:

3

4

7             9             2             4

3             2             5             4

9             7             8             1

Output:

2             4             7             9

2             3             4             5

1             7             8             9

```import java.io.*;

class Sort2DMatrix {

static int[][] Sort2DArraysByRow(int m,int n,int arr[][])
{

for (int i = 0; i < m; i++)
{
for (int j = 0; j < n; j++)
{
for (int k = 0; k < n - j - 1; k++)
{
if (arr[i][k] > arr[i][k + 1])
{
int t = arr[i][k];
arr[i][k] = arr[i][k + 1];
arr[i][k + 1] = t;
}
}
}
}
return arr;
}

public static void main(String args[])
{
int m=3,n=4;
int arr[][] = { { 7,9,2,4 },{ 3,2,5,4 },{ 9,7,8,1 } };

int[][] ar=new int[m][n];

ar=Sort2DArraysByRow(m,n,arr);

for (int i = 0; i < 3; i++) {
for (int j = 0; j < 4; j++)
System.out.print(ar[i][j] + " ");
System.out.println();
}
}
}
/*
OUTPUT
2 4 7 9
2 3 4 5
1 7 8 9
*/
```
