# Row wise sorting in 2D array

Given a 2D array, sort each row of this array and print the result.

Examples:

```Input :
77 11 22 3
11 89 1 12
32 11 56 7
11 22 44 33
Output :
3 11 22 77
1 11 12 89
7 11 32 56
11 22 33 44

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

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Method 1 (Using Bubble Sort)
Start iterating through each row of given 2D array, and sort elements of each row using efficient sorting algorithm.

## Java

 `// Java code to sort 2D matrix row-wise ` `import` `java.io.*; ` ` `  `public` `class` `Sort2DMatrix { ` ` `  `    ``static` `int` `sortRowWise(``int` `m[][]) ` `    ``{ ` `        ``// loop for rows of matrix ` `        ``for` `(``int` `i = ``0``; i < m.length; i++) { ` ` `  `            ``// loop for column of matrix ` `            ``for` `(``int` `j = ``0``; j < m[i].length; j++) { ` ` `  `                ``// loop for comparison and swapping ` `                ``for` `(``int` `k = ``0``; k < m[i].length - j - ``1``; k++) { ` `                    ``if` `(m[i][k] > m[i][k + ``1``]) { ` ` `  `                        ``// swapping of elements ` `                        ``int` `t = m[i][k]; ` `                        ``m[i][k] = m[i][k + ``1``]; ` `                        ``m[i][k + ``1``] = t; ` `                    ``} ` `                ``} ` `            ``} ` `        ``} ` ` `  `        ``// printing the sorted matrix ` `        ``for` `(``int` `i = ``0``; i < m.length; i++) { ` `            ``for` `(``int` `j = ``0``; j < m[i].length; j++) ` `                ``System.out.print(m[i][j] + ``" "``); ` `            ``System.out.println(); ` `        ``} ` ` `  `        ``return` `0``; ` `    ``} ` ` `  `    ``// driver code ` `    ``public` `static` `void` `main(String args[]) ` `    ``{ ` `        ``int` `m[][] = { { ``9``, ``8``, ``7``, ``1` `}, ` `                      ``{ ``7``, ``3``, ``0``, ``2` `}, ` `                      ``{ ``9``, ``5``, ``3``, ``2` `}, ` `                      ``{ ``6``, ``3``, ``1``, ``2` `} }; ` `        ``sortRowWise(m); ` `    ``} ` `} `

Output

```1 7 8 9
0 2 3 7
2 3 5 9
1 2 3 6
```

Method 2 (Using Library Function)
The idea is to use Arrays.sort() for every row of matrix.

## Java

 `// Java code to sort 2D matrix row-wise ` `import` `java.io.*; ` `import` `java.util.Arrays; ` ` `  `public` `class` `Sort2DMatrix { ` ` `  `    ``static` `int` `sortRowWise(``int` `m[][]) ` `    ``{ ` `        ``// One by one sort individual rows. ` `        ``for` `(``int` `i = ``0``; i < m.length; i++) ` `            ``Arrays.sort(m[i]); ` ` `  `        ``// printing the sorted matrix ` `        ``for` `(``int` `i = ``0``; i < m.length; i++) { ` `            ``for` `(``int` `j = ``0``; j < m[i].length; j++) ` `                ``System.out.print(m[i][j] + ``" "``); ` `            ``System.out.println(); ` `        ``} ` ` `  `        ``return` `0``; ` `    ``} ` ` `  `    ``// driver code ` `    ``public` `static` `void` `main(String args[]) ` `    ``{ ` `        ``int` `m[][] = { { ``9``, ``8``, ``7``, ``1` `}, ` `                      ``{ ``7``, ``3``, ``0``, ``2` `}, ` `                      ``{ ``9``, ``5``, ``3``, ``2` `}, ` `                      ``{ ``6``, ``3``, ``1``, ``2` `} }; ` ` `  `        ``sortRowWise(m); ` `    ``} ` `} `

Output

```1 7 8 9
0 2 3 7
2 3 5 9
1 2 3 6
```
