A Simple Counting Problem

Revision en1, by harsh-apcr, 2024-06-07 19:23:57

You're given a list of points $$$(x_1, y_1), \ldots, (x_n, y_n)$$$

There are two kinds of queries

  1. Insert a new point in this list
  2. Given $$$(x, y)$$$ and you need to count number of points in the given list with $$$x_i \leq x$$$ and $$$y_i \leq y$$$

you can expect the constraints to be $$$n \leq 10^5$$$ and $$$0 \leq x_i, y_i, x, y \leq 10^9$$$

Any help is appreciated, Thanks
