How can I decide to move towards large values or small values?

[@chinthalasundarramireddy6048]

That's our choice

[@chinmaydeshmukh7631]

That mentioned in the question.

[@jaytravels4113]

is it, from smallest or largest??

[@hanshernandez5513]

This is the description of C-SCAN. This is not how SCAN works.

[@saiprasadtodkari6006]

It is correct

[@george12121979]

no my friend look - SCAN Seek : 55-93-148-176-180-199-42-27-14 - C-SCAN Seek : 55-93-148-176-180-199-0-14-27-44 See the ZERO on C-SCAN is go to zero and after seek for larger number Total seek on SCAN 329 Total seek on C-SCAN 387 Avg SCAN 329/8=41.125 Avg C-SCAN 385/9=42.77
