Web15 de ene. de 2011 · To switch from an array implementation to a pointer implementation, replace the arr[2*n+1] computation with node.left and arr[2*n+2] with node.right. For parent references such as arr[(n-1)>>1], every node will need a pointer to its parent, node.parent. Alternatively, you can adopt a functional style which makes this all very easy to implement. WebThis mainly involves three steps followed repeatedly to sort the array. 1. Take the root node element and replace it with the last element of the heap. 2. Remove the largest element from the heap. Decrement the size of the heap by one. 3. Apply the heapify algorithm to make it a max-heap again.
