WebApr 11, 2016 · Delete a leaf node. For example, if we want to delete 19 from the above BST example, we can just simply wipe out the link and reclaim the memory by deleting the node and making its parent pointing to NULL (cut the link and wipe out the memory). The BST will still be valid after this node removed. The properties are still conserved. http://icodeguru.com/vc/10book/books/book2/algo032c.htm

WebJan 13, 2012 · The Binary Search is a divide and conquer algorithm: 1) In Divide and Conquer algorithms, we try to solve a problem by solving a smaller sub problem (Divide part) and use the solution to build the solution for our bigger problem (Conquer). 2) Here our problem is to find an element in the sorted array. WebAn optimal binary search tree is a BST, which has minimal expected cost of locating each node. Search time of an element in a BST is O (n), whereas in a Balanced-BST search time is O (log n). Again the search time can be improved in Optimal Cost Binary Search Tree, placing the most frequently used data in the root and closer to the root element ...

WebThe greedy algorithm has only one chance to compute the optimal solution and thus, cannot go back and look at other alternate solutions. However, in many problems, this strategy fails to produce a global optimal solution. Let's consider the following binary tree to understand how a basic greedy algorithm works: WebThe smallest element of a binary search tree is the leftmost element of the tree and the largest element is the rightmost one. So, to find the maximum/minimum element, we have to find the rightmost/leftmost …
