we use this scheme of choosing the rightmost item in the array as the pivot, we’ll need to modify the partitionIt() member function to exclude this rightmost item from the partitioning process. After all, we already know where it should go after the partitioning process is complete: at the partition, between the two groups. Also, once the partitioning process is completed, we need to swap the pivot from the right end into the partition’s location. shows the quickSort1.cpp program, which incorporates these features.
