# Write your MySQL query statement below
WITH
  S AS (
    SELECT
      first_col,
      ROW_NUMBER() OVER (ORDER BY first_col) AS rk
    FROM Data
  ),
  T AS (
    SELECT
      second_col,
      ROW_NUMBER() OVER (ORDER BY second_col DESC) AS rk
    FROM Data
  )
SELECT first_col, second_col
FROM
  S
  JOIN T USING (rk);
