Priority queue greater as function

#1

What does greater do when declare the priority queue to convert it into min heap? How is it helping to convert it into min heap?

#2

@govilayush it is the comparator that the STL uses to put the elements inside the heap. It is a either a max heap or a min heap depending on this comparator. By default it is a max heap and if we provide the greater comparator it behaves like a min heap.
