This straightforward approach involves examining every possible combination to find the solution. While not optimal, this method is simple to understand and implement. However, its time complexity can be high for large datasets, making it inefficient for extensive inputs.
Time Complexity: O(n^2), Space Complexity: O(1)

17The solution examines every possible pair of numbers within the array. It's simple, but not efficient for large datasets.
This technique involves first sorting the array, which allows us to use the two-pointer method to efficiently find the required pairs. This approach is significantly better than brute force for larger datasets.

By sorting the list with sort() and utilizing Python's inherent simplicity, the two-pointer technique effectively finds necessary solutions at improved efficiency for larger inputs.
