Sort function and comparators

#1

how do we know that in comparators, a>b means it will be arranged in descending order and a<b means it will be arranged ascending order???
i am so confused!

#2

compare function is called when you have to check whether two nos are swapped or not

if you return
return a<b
means return true if a is smaller
means smaller no comes first because it is swapped

whenever you want to swap you return true else false

i hope this helps
