A clique of size k is a subgraph that consists of k vertices that are all connected to each via an edge, i.e., all k(k1)/2 edges exists. In class we proved that the problem of finding whether a graph contains a k -elique is NP-complete. Consider a similar problem: a k -clique with spikes consists of 2k vertices such that the first k elements form a clique and the rest k vertices are connected via an edge a different vertex of the clique. onsider a similar problem: Given a graph G and a number k find whether a k -clique with spikes exists. Show that the problem is NP-conplete.

You want to know which files are large files (at least 0.1MB) in your data directory, but you do not want to go through them one by one. So you decide to design a regular expression to help with this. Locate the rule under the p1 target in your Makefile. This rule uses the Is command to list the contents of the data directory in your current folder. The -I option produces the long listing for these contents, which includes their size in bytes. The output of this is command is then piped as input into grep command. The-E option for the grep command allows searching through this text with a regular expression. Replace the regular expression in this grep command to search for any 6 digit number. Since the size of these files are displayed in bytes, the smallest possible six digit number: 100000 corresponds to 0.1MB. When this regular expression is correct, running "make p1" should display the three large files that can be found within the provided data directory. Tip: Start by composing a regex that matches any single digit, and test this to make sure that it works as expected. If you encounter trouble with one specific way of matching single digits, like \d, then please try to find another way that works with grep - E. Once this is working, look for a way to extend this pattern so that it must be repeated exactly six times to be matched.
