There is a Database of different coloured animals..You want to see only white cats.This task can be carried out by the sorting the data according to:
- Colour.then Gender
- Pet Type ,then colour✅
- Pet Type,then Gender
- Colour,then Pet Name
First we set the sort function in such a way so as to show only those records which have Pet Type as Cat and then we again use the sort functions to show only those records that have colour as white.Thus in the end we will have only white cats displayed."
