Merging Segment Trees: Implementation and Applications
Segment Tree Merging Fundamentals
Segment tree merging combines two segment trees into one. The core algorithm processes corresponding nodes:
If either node is empty, return the other
Otherwise, recursively merge left and right subtrees
Node* merge(Node* x, Node* y) {
if (!x) return y;
if (!y) return x;
x->value += y->v ...
