Hi sir, why do you pass compare function as a parameter while we can just calling it like any regular function??
Comparators _understanding the working
hello @mzk1994
by default sort function order the elemnts in ascending order.
but if we want to order them in some different order then comparators are needed .
inside comparators we write how we want to order any two entries in our container .
u can call but then it will work only for two numbers.
we have array which can have so many numbers .
read this documentation of sort function for better clarity->
