Q. Show that the decision problem ISD is NP-complete. Provide complete proof that ISD is in complexity class NP, by defining a suitable certificate and presenting and analyzing a certificate verification algorithm for the certificate you defined. Then prove that it is NP-hard by reducing from vertex-cover decision problem (i.e. show how an instance of vertex cover can be decided with one call to a decider for ISD).
