Segment Trees are a powerful data structure in computer science, designed for efficient range query optimization. They excel in tasks such as finding sums, minimums, or maximums within subarrays, with a complexity of O(log n) for queries and updates. This text delves into their applications across technology, from computer graphics to databases, and discusses implementations in Python, Java, and C++. Advanced techniques like Lazy Propagation and multidimensional trees are also covered.
