Tree terminologies
Tree : Tree is collection of nodes and edges. Or, it's collection of nodes where one node is taken as root node and rest of the nodes are divided into disjoint subsets and each subset is tree or subtree. Tree terminologies : Level starts from 1 onwards (we count nodes) and height starts from 0 onwards (we counts edges). Binary Tree : A tree that can have 0, 1 or 2 sub trees, is called binary tree. How many binary trees can be generated from given number of nodes (n)? 1. Unlabelled Nodes : How many trees with maximum height? 2. Labelled Nodes : Height vs Nodes Formula : 1. If height of binary tree is given? Minimum No. of Nodes (n) = h + 1 Maximum No. of Nodes (n) = 2^(n+1) - 1 2. If nodes of binary tree is given? Minimum Height (h) = log(n+1) - 1 Maximum Height (h) = n-1 Relationship b/w nodes with degree 0 and degree 2: Number of nodes with degree(0) = Number of nodes with degree(2) + 1
gsutil Vs Storage Transfer Service Vs Transfer Appliance
When transferring data from an on-premiss location, use gsutil When transferring data from another cloud storage provider, use storage transfer service gsutil is a Python application that lets you access Cloud Storage from the command line. You can use gsutil to do a wide range of bucket and object management tasks, including: Creating and deleting buckets. Uploading, downloading, and deleting objects. Listing buckets and objects. Moving, copying, and renaming objects. Editing object and bucket ACLs. gsutil performs all operations, including uploads and downloads, using HTTPS and transport-layer security (TLS). For a complete list of guides to completing tasks with gsutil, see Cloud Storage How-to Guides . Storage Transfer Service is a product that enables you to: Move or backup data to a Cloud Storage bucket either from other cloud storage providers or from your on-premises storage. Move data from one Cloud Storage bucket to another, so that it is available to differe...
