Describe the complexity (order) of deletion from a B-tree.
What will be an ideal response?
Like insertion, the complexity of deletion from a B-tree is logarithmic. That is, O(log n). Because the ripple effect of a deletion affects no more than one path from the root to a leaf, the complexity is equal to the height of the tree, which is log n for a tree of n nodes.
