When it is understood that HHH does simulate itself
simulating DDD then any first year CS student knows
that when each of the above are correctly simulated
by HHH that none of them ever stop running unless aborted.
(recursive simulation is similar to infinite recursion).

The same thing equally applies to these two, yet they may

 I am only asking whether or not people here can understand
that when each of the above functions are correctly simulated
by simulating termination analyzer HHH that they would never
stop running unless aborted. *Please start with the first three*
