text: function to sort each row of the matrix according to the order specified by descending .
code: static void sortByRow ( int [ ] [ ] mat , int n , boolean descending ) { int temp = 0 ; for ( int i = 0 ; i < n ; i ++ ) { if ( descending == true ) { int t = i ; for ( int p = 0 ; p < n ; p ++ ) { for ( int j = p + 1 ; j < n ; j ++ ) { if ( mat [ t ] [ p ] < mat [ t ] [ j ] ) { temp = mat [ t ] [ p ] ; mat [ t ] [ p ] = mat [ t ] [ j ] ; mat [ t ] [ j ] = temp ; } } } } else Arrays . sort ( mat [ i ] ) ; } }
