e-Tree is a portable Christmas tree perfect for all geeks. A fun way to show some Christmas cheer while keeping it geeky.
Following is C/C++ implementation for optimal BST problem using Dynamic Programming. We use an auxiliary array cost[n][n] to store the solutions of subproblems. cost[0][n-1] will hold the final result. The challenge in implementation is, all diagonal values must be filled first, then the ...
The parallel port usually comes as a 25-pin female port and it is commonly used to connect printers to a computer. Many geeks also use it to connect their own devices to their PCs. There is a few more things to remember when using a PC’s Parallel Port. It can load only 2.5mA and...
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. ...
[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....
[geeksforgeeks] Bottom View of a Binary Tree Bottom View of a Binary Tree Given a Binary Tree, we need to print the bottom view from left to right.A node x is there in output if x is the bottommost node at its horizontal distance. Horizontal distance of left child of a node x is...
Solution 1. Recursion For two trees t1 and t2 to be mirror of each other, the following three conditions must be true 1. their root node's value must be the same. 2. t1's left subtree must be mirror of t2's right subtree.
http://www.geeksforgeeks.org/lowest-common-ancestor-in-a-binary-search-tree/ Lowest Common Ancestor in a Binary Search Tree. Given values of two nodes in a Binary Search Tree, write a c program to find theLowestCommonAncestor (LCA). You may assume that both the values exist in the tree...
