Little Muffin and Big Data

Muffin started to run his video blog with the hyped-up name “Videoblob”. He talks about food for cats, techniques for sudden jumps off the wall, about clever methods of catching flies and hunting birds from the windowsill.

Muffin wants to know if his content is interesting for other cats, because video blogging takes a lot of effort. That’s why he started a visitor counter.

You need to write a program that will help Muffin evaluate his traffic. On different days, a different number of people can visit the blog, but the main thing is that the average number of visits at first stays above 1,000. If traffic falls, the program will need to notify Muffin.

Muffin has already sent you traffic data for the first three days, and the figures are stored in variables. The recommended average traffic value is stored in the variable expectedUsers.

To track blog popularity and changes in traffic, Muffin bought a program from third-party developers that draws values on a graph. You can start this program with a special command muffin.plot().

The command builds the graph based on all the passed arguments, except the last one. The last value is drawn as a horizontal line so that it is possible to estimate how far each of the points in the graph deviates from the recommended value.
