100% matlab code .. optimised to get 4,2,1 pattern

%Can be optimised as follows

p=4+ceil(rand*20) %choosing a integer between & including 5 and  24 

count=0;

while(count<3) %% after few recurrences of the pattern 4,2,1 we wish to stop

 if (mod(p,2)==0)

  p=p/2

 else

  p=3*p+1

 end

 if(p==1)

  count=count+1;

 end

end

disp('lets stop now as we noticed it is giving 4,2,1 sequence as a loop')
