Suppose you're choosing a university to attend, and you'd like to quantifyhow dissimilarany twouniversities are. You rate each university you're considering on several numerical traits. You decide on a verydetailed list of 1000 traits, and you measure all of them! Some examples:

The cost to attend (per year).
The average Yelp review of nearby Thai restaurants.
The USA Today ranking of the Medical school.
The USA Today ranking of the Engineering school.

You decide that the dissimilarity between two universities is the totalof the differences in their traits. That is, thedissimilarity is:

the sum of
the absolute values of
the 1000 differences in their trait values.

In the next cell, we've loaded arrays containing the 1000 trait values for Stanford and Berkeley. Compute the dissimilarity (according to the above technique) between Stanford and Berkeley. Call your answer dissimilarity. Use a single line of code to compute the answer.
