    Question

    In a perfectly balanced Binary Search Tree with N nodes,

    what is the worst-case time complexity for searching for an element?
    A O(1) Correct Answer Incorrect Answer
    B O(log N) Correct Answer Incorrect Answer
    C O(N) Correct Answer Incorrect Answer
    D O(N log N) Correct Answer Incorrect Answer
    E O(N²) Correct Answer Incorrect Answer

    Solution

    In a perfectly balanced BST, the height of the tree is approximately log N. Since search operations traverse a path from the root to a leaf, the worst-case time complexity is proportional to the height, hence O(log N).
