Algorithms: CSE 101 — Homework IV Solve the following problems. Consult the style guide for writing solutions. Each problem is worth 10 points. Problem 1: Covering a spectrum You want to create a scientific laboratory capable of monitoring any frequency in the electromag- netic spectrum between L and H . You have a list of possible monitoring technologies, T i , i = 1 , ..n , each with an interval [ l i , h i ] of frequencies that it can be used to monitor. You want to pick as few as possible technologies that together cover the interval [ L, H ]. Give an efficient algorithm for finding such a set of technologies. Problem 2: Coupons Consider the following ”coupon collector” problem. There are different varieties of cereal, and each comes with a single coupon for a discount on another box of cereal, perhaps of another variety. You can use multiple coupons when purchasing a new box, up to getting the new box free, but you never get money back. You want to buy one box of each variety, for as little money as possible.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
