                    5. The following program code sorts the columns of a double dimensional array in descending order using Bubble Sort technique.
                      There are some places in the code marked as ?1?, ?2?, ?3?, ?4? and ?5? which are to be replaced by a statement/expression so
                      that the code works properly.
                        void sortcol(int M[][])
                            {     int r=M.length;
                                  int c=?1?;
                                  int t;
                                       for(int k=0; ?2?; k++)
                                             for(int i=0;i<r;i++)
                                                  for(int j=0;j<r-1;j++)
