I need to query all the details from virtual machine and update into the MongoDB. Which require the output look like this. { "_id" : ObjectId("5800509f23888a12bccf2347"), "ResourceGrp" : "XYZZ-MachineGrp", "ProcessTime" : ISODate(&q...

A* (A star) is a search algorithm that is used for finding path from one node to another. So it can be compared with Breadth First Search, or Dijkstra’s algorithm, or Depth First Search, or Best First Search. A* algorithm is widely used in graph search for being better in efficiency and accuracy, wh...

foo = frozenset(["bar", 1, "Hello!"]) foo[2] = 7 # ERROR foo.add(3) # ERROR Second line would return an error since frozenset members once created aren't assignable. Third line would return error as frozensets do not support functions that can manipulate members.

Rabin-Karp Algorithm is a string searching algorithm created by Richard M. Karp and Michael O. Rabin that uses hashing to find any one of a set of pattern strings in a text. A substring of a string is another string that occurs in. For example, ver is a substring of stackoverflow. Not to be confuse...
