Segment Tree Implementation for Maximum Subarray Sum Queries
Given an array of n elements arr_1, arr_2, ..., arr_n, support q operations:
Type 1: Update arr_x = value
Type 2: Query maximum subarray sum in range [l, r]
Information to Maintain
To solve this problem using divide and conquer, we need to determine what information can be merged to compute the required result.
The maximum subarray sum in a r ...
