text: Sort the matrix row | Java implementation to sort the matrix row - wise and column - wise ; function to sort each row of the matrix ; sorting row number ' i ' ; function to find transpose of the matrix ; swapping element at index ( i , j ) by element at index ( j , i ) ; function to sort the matrix row - wise and column - wise ; sort rows of mat [ ] [ ] ; get transpose of mat [ ] [ ] ; again sort rows of mat [ ] [ ] ; again get transpose of mat [ ] [ ] ; function to print the matrix ; Driver code
