Given a MxN matrix. Print the elements in odd rows from left to right and the elements in even rows from right to left.(Java or C++)

given the array arr[][]:

 bool leftToRight = true;

 for (int i=0; i<M; i++)

   {

       if (leftToRight)

       {

           for (int j=0; j<N; j++)

               printf("%d ", arr[i][j]);

       }

       else

       {

           for (int j=N-1; j>=0; j--)

               printf("%d ",arr[i][j]);

       }

       leftToRight = !leftToRight;

   }

answer; technician (b) is wrong; so im thinking technician (a) is correct; good luck
