Sir,

How to find the no. of repeated sequence (letters) in the given sentence.

for example, a="I want THAAAAAT APPPPPLE ):):):";

The No. of repeated sequences are: 3

2. APPPPPLE

3. ):):):

thanks

a='I want THAAAAAT APPPPPLE ):):):'
s=regexp(a,'\s+','split')
out=s(~cellfun(@(x) numel(unique(x))==numel(x),s))

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.
