Kindly comment out the errors

Hello @mkidwai74
U havent declared 2d vector correctly.

Correct it and it will work

@mkidwai74
since u r using custom class , u have to define ur own compariosn logic for priority queue ( define functor) .

if u dont want to define that then pls use pair class(predefined) of c++
