Update max diff during the journey. Do this for every node and its ancestors. Approach Summary (Optimal Approach) - The key function is maxAncestorDiff, which initializes minimum and maximum values and then calls the recursive function findMaxDiff to compute the maximum difference between any two nodes in the binary tree. The findMaxDiff function traverses the tree recursively, updating the minimum and maximum values encountered along the way, and computes the maximum difference for each subtree. The final result is the maximum difference obtained across all subtrees, and it represents the maximum absolute difference between any two nodes in the given binary tree. ╔═╦╗╔╦╗╔═╦═╦╦╦╦╗╔═╗ ║╚╣║║║╚╣╚╣╔╣╔╣║╚╣═╣ ╠╗║╚╝║║╠╗║╚╣║║║║║═╣ ╚═╩══╩═╩═╩═╩╝╚╩═╩═╝  Timelines 00:00 - Introduction #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge #leetcodequestions #leetcodechallenge #hindi #india #coding #helpajobseeker #easyrecipes #leetcode #leetcodequestionandanswers #leetcodesolution #leetcodedailychallenge#leetcodequestions #leetcodechallenge #hindi #india #hindiexplanation #hindiexplained #easyexplaination #interview#interviewtips #interviewpreparation #interview_ds_algo #hinglish #github #design #data #google #video #instagram #facebook #leetcode #computerscience #leetcodesolutions #leetcodequestionandanswers #code #learning #dsalgo #dsa #2024 #newyear
