Performing a range query with k elements occurring within the range requires O(logbn + k) operations in the worst case. [edit] Implementation The leaves (the bottom-most index blocks) of the B+ tree are often linked to one another in a linked list; this makes range queries or an (orde...
In the above tree to delete node 6 with two children, we first find the inorder successor for that node to be deleted. We find the in-order successor by finding the minimum value in the right subtree. In the above case, the minimum value is 7 in the right subtree. We copy it to ...

and as I don't like pointers(also pointer based implementations are often slower than array based ones because of the dynamic memory allocation), I implemented it myself. Here is the implementation:https://github.com/thisIsMorningstar/Competitive_Programming/blob/main/templates/wavelet_tree.cpp ...

. Compared to the original prefix sums solution, the bottom-up segment tree uses 47 ms in total, and the parallel implementation uses only 16 ms in total. Thus, even in such a simple problem with only prefix queries the novel implementation is 3x faster than the state of art even in ...
