WebThe search for an interval that overlaps i starts with x at the root of the tree and proceeds downward. It terminates when either an overlapping interval is found or x becomes NIL. Since each iteration of the basic loop takes O(1) time, and since the height of an n-node red-black tree is O(lg n), the INTERVAL-SEARCH procedure takes O(lg n) time.

WebMy assignment defines an interval tree as a binary search tree ordered by the left endpoints of the intervals. Each node also stores the maximum right endpoint from the subtree rooted at that node. In that case you could have an interval that contains I while its parent doesn't, right?
