Highest response ratio next (HRRN) scheduling is a non-preemptive discipline, similar to shortest job next (SJN), in which the priority of each job is dependent on its estimated run time, and also the amount of time it has spent waiting.
Jobs gain higher priority the longer they wait, which prevents indefinite waiting or in other words what we say starvation. In fact, the jobs that have spent a long time waiting compete against those estimated to have short run times.$$\text{Priority} = \frac{\text{waiting time}+\text{estimated runtime}}{\text{estimated runtime}} = 1 + \frac{\text{waiting time}}{\text{estimated runtime}}$$So, the conclusion is it gives priority to those processes which have less burst time (or execution time) but also takes care of the waiting time of longer processes,thus preventing starvation.
So, the answer is "shorter , longer"
