Problem

Highmark Health analysts need a state-level view of members with the highest total claim amounts. Write a PostgreSQL query to identify the top five members in each state based on the sum of their claims.

Requirements

  1. Join members to claims and calculate each member's total claim amount.
  2. Rank members separately within each state using a window function.
  3. Return only the top five members per state, ordered by state and rank. Break ties by the lower member_id.
