1. Create a binary search tree by inserting array elements. 2. Perform in order traversal on the bst to get the array elements in sorted order. 1publicclassTreeSort {2publicTreeNode treeSort(TreeNode root,int[] arr) {3if(arr ==null|| arr.length == 0) {4returnroot;5}6for(inti =...
http://www.geeksforgeeks.org/in-place-convert-a-given-binary-tree-to-doubly-linked-list/ Given a Binary Tree (Bt), convert it to a Doubly Linked List(DLL). The left and right pointers in nodes are to be used as previous and next pointers respectively in converted DLL.The order of no...
e-Tree is a portable Christmas tree perfect for all geeks. A fun way to show some Christmas cheer while keeping it geeky.
1) Optimal Substructure: The optimal cost for freq[i..j] can be recursively calculated using following formula. We need to calculateoptCost(0, n-1)to find the result. The idea of above formula is simple, we one by one try all nodes as root (r varies from i to j in second term)....

"You can tell you've been out too long when the geeks start looking good. Knockers, ahhh-" His hand plays with her blouse. The man is unaware, Lorimer realizes. He doesn't know he's drugged, he's speaking his thoughts. I must have done that. Oh, god . . . He takes shelter ...
2) After step 1 sum of left boundary will be stored, now for right part again do the same procedure but now keep going to right as long as right child is available, if not then go to left child and follow same procedure of going right until you reach a leaf node. ...
Given A binary Tree, how do you remove all the half nodes (which has only one child)? Note leaves should not be touched as they have both children as NULL. For example consider the below tree. Nodes 7, 5 and 9 are half nodes as one of their child is Null. We need to remove all...
[GeeksForGeeks] Perfect Binary Tree Given a Binary Tree, write a function to check whether the given Binary Tree is a prefect Binary Tree or not. A Binary tree is Perfect Binary Tree in which all internal nodes have two children and all leaves are at same level....
