Output:
The Original set of numbers are:
70 13 10 36 78 98 18 64 60 84
The two sequences are:
{ 70 13 10 36 78 98 18 64 } and { 60 84 }
Partitioning around index 8
The Original set of characters are:
n p r e m z y o x p
The two sequences are:
{ n p r e m z } and { y o x p }
Partitioning around index 6
