Basic Implementation of Segment Tree

In Basic Implementation of Segment Tree, segment trees are implemented using arrays and linked lists, with two optimization points mentioned at the end: interval update issues and memory optimization for sparse data.

This article will implement a dynamic segment tree DynamicSegmentTree, using "dynamic node opening" to optimize memory usage for sparse data.
