Prims and Kruskals Algorithms

 Explanation Video : We can find spanning trees for connected graphs only.

Prims Algorithm : Select smallest weight edge and always select connected smallest one.

Kruskals Algorithms : Select all (connected or not connected) minimum cost edges that don't form a circle and form a tree. It may find minimum weight tree from the given unconnected graph but that may not be spanning tree.

Find missing edge
In a given graph there can be more than one spanning trees that gives optimum result but there can be only one optimum result for spanning tree in a given graph.

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...
