A typical file-processing system is supported by a conventional operating system. The system stores permanent records in various files, and it needs different application programs to extract records from, and add records to, the appropriate files. Keeping organizational information in a file-processing system has a number of major disadvantages. Which one from the choices is not a disadvantage of a typical file-processing system?

Consider the Subgraph Isomorphism problem: Input: two undirected graphs G and H.Output: determine whether G is a subgraph of H (that is, whether by deleting certain vertices and edges of H we obtain a graph that is, up to renaming of vertices, identical to G). The Subgraph Isomorphism problem can be shown to be NP-hard because it is a generalization of
