Web10 jan. 2024 · A Min Heap is a Complete Binary Tree. A Min heap is typically represented as an array. The root element will be at Arr [0]. For any ith node, i.e., Arr [i]: Arr [ (i -1) / 2] returns its parent node. Arr [ (2 * i) + 1] returns its left child node. Arr [ (2 * i) + 2] returns its right child node.

Web$\begingroup$ @MarceloFornet I don't see how you get to the 2n+1 formula from that though, take for example 5. It has 2 elements to it's left, so in the next level there should be 4 elements to the left of it's first child.
