Identify Overlapping Sessions and Optimize Coverage
Problem Statement: Overlapping User Sessions for Fraud Detection
In the context of fraud detection pipelines, it's crucial to accurately reconcile user activity windows. You are given a list of login sessions for a single user. Each session is represented as [start_time, end_time].
Your task is twofold:
- Overlap Detection: Determine if any of the given sessions overlap.
- Optimal Session Reconciliation: If overlaps exist, identify and return the minimal set of session IDs to remove such that all remaining sessions are non-overlapping. The objective is to maximize the total time covered by the remaining, non-overlapping sessions.
