Grid Illumination: Given an NxN grid with an array of lamp coordinates. Each lamp provides illumination to every square on their x axis, every square on their y axis, and every square that lies in their diagonal (think of a Queen in chess). Given an array of query coordinates, determine whether that point is illuminated or not. The catch is when checking a query all lamps adjacent to, or on, that query get turned off. The ranges for the variables/arrays were about: 10^3 < N < 10^9, 10^3 < lamps < 10^9, 10^3 < queries < 10^9.
Given a 1TB file of serialized 4 byte integers, and 2GB of ram, sort the integers into a resulting 1TB file. My interviewer was very collaborative in entertaining various solution ideas until we came up with a combo that would work performantly and reduce the number of passes over the 1TB file and intermediate files.
