Consider a weighted version of the class scheduling problem, where different classes offer different number of credit hours (totally unrelated to the duration of the class lectures). your goal is now to choose a set of non-conflicting classes that give you the largest possible number of credit hours, given arrays of start times, end times, and credit hours as input.

Jasper and samantha are in a robotics competition. the guidelines state that the robots should be able to move a 10-gram weight at least 2 meters and turn in a circle. jasper and samantha have already built the robot. which step of the design process should they follow next to decide whether their robot meets the minimum criteria for the competition?

Look at the far left lane in the picture. explain what the red car is doing and what it needs to do to travel safely.

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)
