Array's and strings are immutable..ie...the same array and
string cannot be increased or decreased but a new memory(a
new size can be declared here) is allocated and by using the
preserve keyword the old data is copied onto to the new array.

Now copying from old to new is lengthy procedure...though it
happens internally it will still have a major impact on the
performance of the program. To overcome this we can go for
Collections in Array's and String builder for strings.
