Again, calculate the minimum number of bills or coins required for a given amount of money (change). This time we will use a Go map instead of a csv string converted to a structure.

This time just a simple example of grading scores (0 - 100) with letters (A - F). Two approaches are presented, one using switch/case in an "on the fly" function, and the other uses the score as an index to a string of letters F through A.

Reading the content of a web page with a given URL is pretty simple with Go. Here we defer the closing of the response body (at an early point, so we won't later forget) until the program exits.

# Is {(1,1), (2,2), (3,3)} symmetric? transitive? Yes! Yes! ## Why is R = {(1,2), (2,3), (1,3), (2,1)} not transitive? Because (1,1) and (2,2) are missing. ## #
