Leetcode POTD
First calculated total sum of BT. After that implemented postorder DFS traversal to calculate subtree sum at each node. Using that found maximum product by subtreeSum*(totalSum-subtreeSum). Time Complexity is O(n) due to traversing all nodes.

Leetcode POTD
The question is easy just applied level order traversal and calculated sum of each level and returned the lowest level with the maximum sum.

LeetCode POTD β
Sorted matrix β brute force.
Used bottom-left traversal to count negatives.
π O(n + m)
π§ O(1)
Constraints are hints, not decorations π

Struggling hard today for better tomorrow
𧩠Problem: Maximum Difference by Remapping a Digit
π Greedy approach:
β’ Max β Replace first non-9 with 9
β’ Min β Replace first digit with 0 (leading zeros allowed)
