{
return a>b;
}
then this function sort in increasing or decreasing ?? please explain… and what it return …
Please explain briefly
@AMIT_KUMAR
Comparator should return a boolean value in every case.
a<b is a boolean value since it returns true/false according to the values of a and b.
You can learn it as a fact, that in the comparator (T a, T b)
if you want to sort in increasing order you do a < b.
if you want to sort in decreasing order you do a > b.
