WebApr 15, 2015 · 3. In the windowing query, given a set of line segments and an axis-aligned rectangle, we have to find the intersections of the line segments with the rectangle. This can be solved by using Interval Trees in combination with Range Trees. Range Trees are an efficient data structure for finding the set of points present within a Range/Rectangle. WebCartesian trees have found numerous applications due to a peculiar rigid structure whose properties can be exploited in various ways. chipkartenleser cherry smartterminal st-2100
