Harder Test Problems

On a recent Wells Fargo campus coding test, the last question is usually the hard one, and because it comes after two quicker items on the same clock, you often reach it short of time. Expect medium to hard. Each problem here has a known method that fits its limits.

Two of the four are dynamic programs in disguise, one over a budget and one over time. The other two are a graph walk and a sweep over points in the plane. Work out which kind you have early, so the minutes you have left go into typing it carefully.

Before you write the real solution, put the brute force and its cost in a comment. Then check the limits. They tell you why it won't pass. Start with the budget problem below, since it comes up most and has the shortest code, and save the graph and geometry problems for after, reading each statement twice because each one turns on a single edge rule.
