Problem 1 - Tamper-Evident System Log Chains Problem Statement You are building an audit trail analyzer for contract verification logs. You are given an integer array activityLogs, where each value represents a security hash weight associated with a system event. Your task is to identify a contiguous subarray whose cumulative sum is maximized. Return the maximum subarray sum. Constraints Constraint 1 ≤ N ≤ 105 -104 ≤ activityLogs[i] ≤ 104 Test Cases Input Output Explanation activityLogs = [-2, 1, -3, ...
