Constructing the Segment Tree

Segment Tree construction involves determining values for nodes and defining the merge operation. Leaf nodes store array elements, while parent nodes represent merged child node values for specific ranges. The process starts from leaves and builds recursively upwards. If the merge operation is constant time, the tree is constructed in O(N). This approach optimizes range query solutions efficiently.
