Effectively we just did a range update on the abstract arrayRSQand the range update is equivalent to addinguto all elements of arrayRSQfrom l to N. But we wanted the range update to be only for the range [l,r], so we should now do a range update in which we subtractufrom [r+1,...

Path Queries 1 , could be solved using Tree flattening and Segment tree . The basic idea is that change in value of node 's' changes only the values of all nodes in its subtree , so we can use range update , point query segment tree to solve it in O(NlogN) AC solution → Reply...

We can use two point-update, range-minimum-query segment trees to achieve this. One stores pi−ipi−i and the other stores pi+ipi+i. → Reply kgargdun 4 years ago, # ^ | 0 thanks! → Reply kgargdun 4 years ago, # | 0 Auto comment: topic has been updated by kg...
I'm learning segment trees, and for now I'm focused on "standard" range query/point update segment trees. I've tried to solve CSES 1144 : Salary Queries, but I keep getting TLE. I've written a simple segment tree struct, and I'm using coordinate compression. I suppose that I should...

Here, you'll find efficient and well-commented C++ solutions to a wide range of algorithmic and data structure problems from the CSES problem set. What is CSES? CSES is a popular resource for practicing and honing algorithmic problem-solving skills. It offers a vast collection of problems ...
Now the little modification is that we create the segment tree array (say tree) of user-defined data type struct{ value, index}, hence, for the vertex v, tree[v].value gives the maximum rooms in the range that the vertex v holds and tree[v].index is the corresponding hotel's array...
