yes, ascending order is commonly used to arrange elements in a binary search tree. in a binary search tree, each left child node has a lesser value than its parent node, while each right child node has a greater value. this arrangement allows for efficient searching and traversal of the ...
A tree data structure is a fundamental, or node-based, hierarchical arrangement of elements with parent-child relationships between each node. Every other node in the tree is either a leaf node, which has no children, or an internal node, which has at least one child. The topmost node is...
I've been a little busy playing with melding Andy Gordon's fold implementation and Peter's tree traversal (_tt), and have put together versions of reduce/fold/scan (left and right) using both methodologies; well, almost, I've gone cross-eyed on doing the tree traversa...
The new __init_subclass__ classmethod will be called on the base class whenever a new subclass is created: class PluginBase: subclasses = [] def __init_subclass__(cls, **kwargs): super().__init_subclass__(**kwargs) cls.subclasses.append(cls) class Plugin1(PluginBase): pass class ...
In 5.7 the optimizer avoids creating a temporary table for the result of UNION ALL queries when there is no need for it, i.e., when there is no top-level ORDER BY clause. This reduces the need for disk space and disk I/O when executing large unions, and perhaps even more important,...
