What is a segment tree and what are its goals?
Expert Solution
Step 1
Introduction:
A segment tree is a data structure that handles several queries over an array. It employs a divide-and-conquer strategy. Range minimum and maximum & Sum Queries and Range Update Queries are solved in O (log n) time complexity.
Range Min/Max & Sum Queries and Range Update Queries may be solved in O (log n) time using Segment Trees. The Segment Tree approach may readily handle these issues. We may investigate this strategy by efficiently resolving such an issue.
