There are a lot of trees in the world so we should be protecting them not cutting them down. We wouldn’t be alive if there was no trees because trees really keep us people alive. So we should be minding them!!!. Computational Geometry (EECS 396/496) – October 9th, 2017. Recap – The Range Query Problem. Input. : A collection . of . points . with . ..
