A Scapegoat Tree is a type of self-balancing binary search tree that guarantees O(log n) time complexity for operations. When the tree contains at most m nodes simultaneously, its space complexity can also achieve O(m) due to its special non-pointer memory recycling mechanism. The Scapegoat Tree emp...
