This approach utilizes the two-pointer technique to efficiently solve the problem. By keeping track of two pointers and adjusting them based on certain conditions, we can achieve the desired solution in a more efficient manner.
Time Complexity: O(n)
Space Complexity: O(1)
1def solve(arr):
2 left, right = 0, len(arr) - 1
3 while left < right:
4 # Implement the solution using two-pointer here
5 left += 1
6 right -= 1In Python, we apply the two-pointer technique with simple iteration through list indices.
This approach involves first sorting the input data, then iterating through it to construct the solution. The sorted nature of the data can simplify the logic needed for solving the problem.
Time Complexity: O(n log n) due to sorting
Space Complexity: O(1) if we disregard sorting space

In C, the qsort function is used for sorting. We then iterate over the sorted array to generate the solution.
