In totally, ll are not repeated letter?

[Jothi]

But one problem sir,

The input file is ,

a='I want THAAAAAT APPPPPLE ):):): totally unprepared'

In this input we get

out =

    'THAAAAAT'    'APPPPPLE'    '):):):'    'totally'    'unprepared'

But the required output is,

out =

    'THAAAAAT'    'APPPPPLE'    '):):):'

how to solve this problem.

thank you sir.
