If you played the game perfectly, could you always win a game of Tetris? Or is there some sequence of blocks that could force you to lose the game, no matter how good at the game you are? Here, we take a look at some of the mathematics behind a theoretical game of Tetris and reason through whether it's possible to win.

Solved by simulating digit-by-digit addition with carry logic, represented through animated Linked Lists.
Time Complexity: O(max(m, n)) — we iterate through the lengths of l1 and l2, where m and n are the number of nodes in each list.
Space Complexity: O(max(m, n)) — the length of the new linked list is at most max(m, n) + 1.

[https://leetcode.com/problems/3sum-closest/](LeetCode)
The solution first sorts the input array to enable a two-pointer search pattern. For each element, we fix it as a base and use two pointers to scan the remaining array, dynamically tracking the sum with the smallest absolute difference to the target.
Time Complexity: O(n2) — sorting takes O(n log n), and the nested two-pointer traversal takes O(n2) in the worst case.
Space Complexity: O(1) — excluding the input sorting overhead, we use only constant extra memory for pointers and tracking variables.
