WebJan 19, 2024 · What does Python’s min-heap mean? A min-heap is a collection of nodes. It is one of the heap types. There are two sorts of nodes in a min-heap. A heap contains two nodes: a parent node, or root node, and a child node. A parent or root node’s value should always be less than or equal to the value of the child node in the min-heap. WebTo convert the above recursive procedure into an iterative one, we need an explicit stack. Following is a simple stack-based iterative algorithm to perform preorder traversal: iterativePreorder (node) if (node = null) return s —> empty stack s.push (node) while (not s.isEmpty ()) node —> s.pop () visit (node) if (node.right != null)
