Ranges: 1 ≤ N ≤ 10^3, 1 ≤ M ≤ 10^3, 1 ≤ len(B[i]) ≤ 10^3, -10^9 ≤ B[i][j][0], B[i][j][1] ≤ 10^9, -10^9 ≤ L[0][0], L[0][1], L[1][0], L[1][1] ≤ 10^9, -10^9 ≤ P[0], P[1] ≤ 10^9  
Addtl Info: B is a list of size N, each element is a list of tuples (x, y) representing the vertices of a polygon. L is a tuple of two tuples, each representing a point (x, y) on the dividing line. P is a tuple (x, y) representing the position of the hero.
