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

@@george12121979 I have a doubt about how we will decide the direction...it's always seeking for the highest values or smallest value?how we can decide?

[@zulbirrah3347]

@@Jenifer.manoj20 only SCAN and CSCAN will always move towards higher value first then smaller
