Optimized Approaches for Binary Search Tree Diff Calculations and Tree Ancestry Queries
Minimal Absolute Difference in BST
Since an in-order traversal of a binary search tree produces a sorted sequence, the smallest absolute difference between any two nodes corresponds to the minimal gap between adjacent elements in this sequence. The strategy involves tracking the previously visited node and comparing its value with the current n ...

Dynamic Programming Approaches for Integer Partitioning and Unique BST Generation
Integer Partitioning for Maximum Product
To maximize the product of integers summing up to a target value n, dynamic programming tracks optimal sub-solutions. Define an array maxProduct where maxProduct[val] represents the highest achievable product from partitioning the integer val.
Since partitioning 0 or 1 yields no valid product, the base c ...
