Hackerrank contest

In this problem, we need to calculate the total score of each hacker, where the total score is defined as the sum of their maximum scores across all challenges. We need to exclude all hackers with a total score of 0. The total scores for hackers , , , and can be similarly calculated. It then sums these max scores per hacker and filters out hackers with a total score of 0. This involves two separate groupings, which may increase execution time. However, it also separates concerns and can be easier to understand. It then only includes the highest-ranked i. All three solutions achieve the same result but use different techniques to calculate the total score of each hacker. The second solution separates concerns by creating a CTE for each step, which could improve readability at the cost of execution time. In summary, while different SQL queries can achieve the same result, their performance can vary significantly based on the SQL features and functions used.
