My practice for some important topics of data structures from geeksforgeeks.com using C++ STLs. InsRevLList: Insertion and Reversing the Linked List MergeSortLList: Merge Sort in Linked List Ins_Del_2LList: Insertion and deletion in doubly linked list. Traversing from both the ends inf_to_postf: Infix to postfix IterTowOfHanoi: Iterative tower of Hanoi InorderStack: Inorder traversal of binary tree without recursion AncestorOfNode: Find ancestors of a node in binary tree TreeFromInPre: Construct tree from given pre order and inorder traversal VertSumBinTree: Vertical sum in a given binary tree SumTree: Convert a given tree to its Sum Tree BinFromInorder: Construct Special Binary Tree from given Inorder traversal BinFromPre: Construct a special tree from given preorder traversal LevelOrdTrav: Level order traversal CheckifBin: Check whether a given Binary Tree is Complete or not License This project is licensed under the GNU GENERAL PUBLIC LICENSE - see the LICENSE.txt file for details
