WebHeap data structure is a tree-based structure where the tree is a balanced binary tree in which the root node is compared with its children. The heap function is of two types; they are min-heap and max-heap. In min-heap, the parent node’s value must be less than or equal to both of its child nodes; let’s see with the format as below it ... WebSep 16, 2014 · The algorithm for the delete min operation: Remove the root node. Move the value in the last index of the array (the last leaf in the lowest level of the tree) to the root position (index 0 in the array). The only violation of the heap is at the root. Decrease the array size by 1. Perform BubbleDown operation on the root.
