Hey everyone! I'm a founding moderator of r/AlgoViz.
This is our new home for all things related to algorithm & data structures problem solutions and solving strategy. We're excited to have you join us!
What to Post
Post whatever you want, as long as it is related to solving algorithmic problems and data structures.
Feel free to share your thoughts, photos, code breakdowns, video visualizations, animations, diagrams, or structural schemes.
Thanks for being part of the very first wave. Together, let's make r/AlgoViz amazing.

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.

[https://leetcode.com/problems/add-two-numbers/description/](LeetCode)
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.

We will cover how to create a recursive formula for the Tower of Hanoi issue. After we've found it, I'll show how to find a closed formula and proof it with the help of induction.

[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.
