Please Don’t Skip this question. You were also a newbie programmer once.
I want to know what topics (Data Structures) i need to learn in an order to solve DRGDEN.
- I’ve learnt about segment trees that is basic range sum and minimum query and updates and lazy propagation, i know graphs, trees and basics of them.
- when i saw the editorial i saw many terms like tree flattening, bit tree, fenwick trees, etc, etc
- some people have solved it using segment trees but i could not understand their hundred’s of lines of code
- Please leave below your thoughts on topics need based on how you solved
- if possible leave your code link and some resources
