Maximum length cycle that can be formed by joining two nodes of a binary tree in C++
We are given a binary tree. The goal is to find the maximum length cycle in the given tree. We will do this by finding the maximum height of the left subtree and right subtree from the root node and will join these maximum length paths to get the longest cycle.For the above tree the maximum length cycle is 1-2-3-4-7-6 or 1-6-7-4-3-2-1. The length is 6.Input − treeOutput − Maximum length cycle is − 5Explanation − The max height of left subtree is 3 and of right subtree is 1. Cycle length becomes 3+1+1=5. Cycle is 1-2-3-4-6 or 1-6-4-3-2Input − ...
Read MoreConstruct Tree from given Inorder and Preorder traversals in C++
We are given the Inorder and Preorder traversals of a binary tree. The goal is to construct a tree from given traversals.Inorder traversal − In this type of tree traversal, a left subtree is visited first, followed by the node and right subtree in the end.Inorder (tree root)Traverse left subtree of node pointed by root, call inorder ( root→left )Visit the rootTraverse right subtree of node pointed by root, call inorder ( root→right )Preorder traversal − In this type of tree traversal, the node visited first, followed by the left subtree and right subtree in the end.Preorder (tree root)Visit the ...
Read MoreContinuous Tree in C++
A Continuous Tree is defined as a tree with any path from root node to leaf node has value or weight of nodes such that the absolute difference between the parent node and all of its direct children nodes is always 1.If we pick any node on the path from root to leaf, then|weight of node-weight of left child node|=|weight of left child node-weight of node| = 1, this holds true for right child as well|weight of node-weight of right child node|=|weight lof right child node-weight of node| = 1DiagramLet us understand with examples.The tree below is continuous as absolute ...

If we go by the term Content Management System word to word, then it basically means a system of managing the content. It is defined as a collaborative platform with different features and functionalities that allow the creating, designing, publishing and maintaining web content easily and effectivelWhat is a Content Management System (CMS)?A Content Management System is a software application used to create and design the web content online. It allows the users to manage the digital content easily by providing access to features like database handling, smart reporting, archiving, designing and animation features etc. These are generally used in ...
Read MoreConstruct Turing machine for L = {an bm a(n+m) - n,m≥1} in C++
Turing Machine − A Turing machine is a device used to accept words of a language generated by type 0 grammars. A Turing Machine (TM) is a mathematical model which consists of an infinite length tape divided into cells on which input is given. It consists of a head which reads the input tape. A state register stores the state of the Turing machine. After reading an input symbol, it is replaced with another symbol, its internal state is changed, and it moves from one cell to the right or left. If the TM reaches the final state, the input ...
Read MoreHow to skip a selected test from execution in pytest?
We can skip a selected test from execution in pytest. Pytest is a test framework in python. To install pytest, we need to use the command pip install pytest. After installation, we can verify if python has been installed by the command pytest –version. The version of pytest shall be known.Pytest can be used for creating and executing test cases. It can be used in wide range testing API, UI, database and so on. The test file of pytest has a naming convention that it starts with test_ or ends with _test keyword and every line of code should be ...

We can create a worksheet and then write some values in it. Excel is a spreadsheet which is saved with the .xlsx extension. An excel workbook has multiple sheets and each sheet consists of rows and columns.Out of all the worksheets, while we are accessing a particular sheet that is called as an active sheet. Each cell inside a sheet has a unique address which is a combination of row and column numbers.The column number starts from alphabetic character A and row number starts from the number 1. A cell can contain numerous types of values and they are the ...
