100% matlab prog to stop printing sequence on or before printing 8 numbers

కొన్నిసార్లు 4,2,1 pattern రావటానికి చాలా steps అవసరం కావచ్చు. But if we want to stop after printing just first 8 numbers even if 4,2,1 pattern has  not come by then.. we can use the following

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

count=0;

temp=0;

while(count<2 && temp<7) %% 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

 temp=temp+1;

end

Output:

p =  22

p =  11

p =  34

p =  17

p =  52

p =  26

p =  13

p =  40
