// By case analysis, if we determine the direction
// of person 1, then all other persons have a
// unique direction in order to possibly intersect.
//
// Proof:
// Assume person 1 is at (0, 0), and goes to positive X.
// At time t, can infect at most t units away from (0, 0)
// in Manhattan distance.
//
// If there is a person at (X, Y) at quadrant 1:
// If X > Y: this person must go left, otherwise never hit
// Manhattan bounding box at any time t.
// If X < Y: this person must go down, otherwise never hit
// Manhattan bounding box at any time t.
// If X = Y: this person must go down (if person 1 goes right),
// otherwise never hit Manhattan bounding box at any time t.
//
// Case analysis is the same for all other quadrants.
//
// Fix the direction of person 1. Then, we can count all possible
// intersections by processing the persons' intersections in order.
// We can create 9N nodes: 1 for shortest time to get there, and 8
// for every possible direction. Then, we can run Dijkstra from
// person 1. Take care, that from the original shortest time node,
// we can only go to a node if the distance >= shortest_distance[u].
//
// Time complexity: O(N log N).
