20. Distribute candies in a binary tree
The problem can be found at the following link: Question Link
My Approach
To solve this problem, I followed the subsequent steps:
Traverse the binary tree in a recursive manner.
For each node, calculate the number of candies needed to distribute equally among its left and right subtrees.
Accumulate the total moves required during the traversal.
Time and Auxiliary Space Complexity
Time Complexity: The time complexity of this solution is
O(N)
, where N is the number of nodes in the binary tree. This is because we visit each node once.Auxiliary Space Complexity: The auxiliary space complexity is
O(H)
, where H is the height of the binary tree. This accounts for the recursive call stack.
