# 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
```

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

## C++

 `// C++ code to ` `// sort 2D matrix row-wise` `#include` `using` `namespace` `std;`   `void` `sortRowWise(``int` `m[],` `                 ``int` `r, ``int` `c)` `{` `  ``// loop for rows of matrix` `  ``for` `(``int` `i = 0; i < r; i++) ` `  ``{` `    ``// loop for column of matrix` `    ``for` `(``int` `j = 0; j < c; j++) ` `    ``{` `      ``// loop for comparison and swapping` `      ``for` `(``int` `k = 0; k < c - j - 1; k++) ` `      ``{` `        ``if` `(m[i][k] > m[i][k + 1]) ` `        ``{` `          ``// swapping of elements` `          ``swap(m[i][k], m[i][k + 1]);` `        ``}` `      ``}` `    ``}` `  ``}`   `  ``// printing the sorted matrix` `  ``for` `(``int` `i = 0; i < r; i++) ` `  ``{` `    ``for` `(``int` `j = 0; j < c; j++)` `      ``cout << m[i][j] << ``" "``;` `    ``cout << endl;` `  ``}` `}`   `// Driver code` `int` `main()` `{` `  ``int` `m[] = {{9, 8, 7, 1},` `                ``{7, 3, 0, 2},` `                ``{9, 5, 3, 2},` `                ``{6, 3, 1, 2}};` `  ``int` `r = ``sizeof``(m) / ``sizeof``(m);` `  ``int` `c = ``sizeof``(m) / ``sizeof``(m);` `  ``sortRowWise(m, r, c);` `  ``return` `0;` `}`   `// This code is contributed by Rutvik_56`

## Java

## C#

 `// C# code to sort 2D matrix row-wise` `using` `System;`   `class` `GFG ` `{` `static` `int` `sortRowWise(``int` `[,]m)` `{` `    ``// loop for rows of matrix` `    ``for` `(``int` `i = 0; ` `             ``i < m.GetLength(0); i++)` `    ``{`   `        ``// loop for column of matrix` `        ``for` `(``int` `j = 0; ` `                 ``j < m.GetLength(1); j++) ` `        ``{`   `            ``// loop for comparison and swapping` `            ``for` `(``int` `k = 0; ` `                     ``k < m.GetLength(1) - 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.GetLength(0); i++) ` `    ``{` `        ``for` `(``int` `j = 0;` `                 ``j < m.GetLength(1); j++)` `            ``Console.Write(m[i, j] + ``" "``);` `        ``Console.WriteLine();` `    ``}` `    ``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);` `}` `}`   `// This code is contributed by 29AjayKumar`

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

## C++

 `// C++ code to sort 2D ` `// matrix row-wise` `#include ` `using` `namespace` `std;` `#define M 4` `#define N 4`   `int` `sortRowWise(``int` `m[M][N])` `{` `  ``// One by one sort ` `  ``// individual rows.` `  ``for` `(``int` `i = 0; i < M; i++)` `    ``sort(m[i], m[i] + N);`   `  ``// Printing the sorted matrix` `  ``for` `(``int` `i = 0; i < M; i++) ` `  ``{` `    ``for` `(``int` `j = 0; j < N; j++)` `      ``cout << (m[i][j]) << ``" "``;` `    ``cout << endl;` `  ``}` `}`   `// Driver code` `int` `main()` `{` `  ``int` `m[M][N] = {{9, 8, 7, 1},` `                 ``{7, 3, 0, 2},` `                 ``{9, 5, 3, 2},` `                 ``{6, 3, 1, 2}};` `  ``sortRowWise(m);` `}`   `// This code is contributed by gauravrajput1`

## 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);` `    ``}` `}`

## Python3

 `# Python3 code to sort 2D matrix row-wise` `def` `sortRowWise(m):` `    `  `    ``# One by one sort individual rows.` `    ``for` `i ``in` `range``(``len``(m)): ` `        ``m[i].sort()` `        `  `    ``# printing the sorted matrix` `    ``for` `i ``in` `range``(``len``(m)):` `        ``for` `j ``in` `range``(``len``(m[i])):` `            ``print``(m[i][j], end``=``" "``)` `        ``print``()` `        `  `    ``return` `0`   `# Driver code` `m ``=` `[[``9``, ``8``, ``7``, ``1` `],[``7``, ``3``, ``0``, ``2``],[``9``, ``5``, ``3``, ``2` `],[ ``6``, ``3``, ``1``, ``2``]]`   `sortRowWise(m)`   `# This code is contributed by shubhamsingh10`

Output

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