8. ### What is an algorithm to find if there a k distinct edge weights in a graph? O( m log k )?

Iterate over each edge in the graph (that's the O( m ) part), for each one, adjoin it to a (initially empty) set of weight values you have seen so far (that's the O(log k ) part because of what I explain next). By checking after each set...
