-
 - 3 orders of type buy with price 15 are placed. They are matched with the 3 sell orders with the least price which is 7, and those 3 sell orders are removed from the backlog.
-
 - 999999995 orders of type buy with price 5 are placed. The least price of a sell order is 7, so the 999999995 orders are added to the backlog.

 - 1 order of type sell with price 5 is placed. It is matched with the buy order of the highest price, which is 5, and that buy order is removed from the backlog.

Example 1:

-
 Input: stones = [-1,2,-3,4,-5]
-
 Output: 5
-
 Explanation:
-
 - Alice removes the first 4 stones, adds (-1) + 2 + (-3) + 4 = 2 to her score, and places a stone of
-
   value 2 on the left. stones = [2,-5].
-
 - Bob removes the first 2 stones, adds 2 + (-5) = -3 to his score, and places a stone of value -3 on
-
   the left. stones = [-3].
-
 The difference between their scores is 2 - (-3) = 5.

Example 2:

 Input: stones = [7,-6,5,10,5,-2,-6]

      + + + +## Solutions + + + +### Solution 1: Using Window Functions and Aggregate Functions + +First, we extract the most recent three performance review records for each employee and calculate the difference in rating between each review and the previous one. Next, we filter out employees whose ratings are strictly increasing, and compute their improvement score (i.e., the last rating minus the first rating among the last three reviews). Finally, we sort the results by improvement score in descending order and by name in ascending order. + + + +#### MySQL + +```sql +WITH + recent AS ( + SELECT + employee_id, + rating, + review_date, +
