Time Complexity for tree construction is O(n). There are total 2n-1 nodes, and value of every node is calculated only once in tree construction. Time complexity to query is O(Logn). To query a sum, we process at most four nodes at every level and number of levels is O(Logn). The...
This variation has the same time complexity as the normal segment tree O(log(N))O(log(N)) per query, but might need more memory if you preprocess Logs array. The constant factor is smaller because of the unnecessary nodes we don't visit but in practice the time it takes is not signif...
Segment tree is a data structure which is used for solving range queries in logarithmic time. It is used for storage of Interval or Segment of elements.Interval Interval is a range of elements between the start and end index.Intervals are dynamic as they change during operations. For example,...
we build a complete binary tree on top of our array. modify(pos, f) will replace a[pos] by f(a[pos]), then recompute each of the ancestors of pos by applying + to its two children. This will work with no restrictions on the function f. Its time complexity ...
Moreover, the proposed modification should be capable of performing most general aggregate functions similar to the original Segment Tree, and can also be extended to even higher dimensions. Our proposed algorithm manages to perform range sum queries and updates in O(log2n) time for a 2-...
The number of nodes on this path is bounded by the height of the tree; hence, per the conclusions in the Space section above, the time required for an update is . Query[edit] Consider the set of selected nodes (marked in yellow in the illustration). It is possible, in the case of...

To sum up, the formula is, recursion time complexity = total number of recursion * number of recursion each time, space complexity = recursion depth (that is, the height of the tree) 2) Two recursive calls (focus on the number of recursive calls)Let's look at the following example ...
