WebJan 19, 2024 · 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. When the parent node exceeds the child node ...
