What is this comparator…“greater” does?

#2

hello @garganshul151
greater is inbuilt comparator defined in c++.
its definition is like ->
bool greater(datatype g1,datatype g2){
return g1 > g2;
}

#3

why we have use greater here rather we have to find the smallest of all everytime

#4

yeah , thats why we are using min heap to get smallest element efficiently.

#5

i donot understand the use of ‘greater’ comparator in this code

#6

that is a standard syntax to define min heap.
