The scheduler choice should be a command-line parameter that is one of the following: fcfs, rr, spn, srt, hrrn, fb, all. if all is input, the program should produce output for all six scheduling algorithms. rr and fb should use a quantum of one. fb should use three queues. if more than one job may run next, choose the one with the lowest job name.

Python. primary u. s. interstate highways are numbered 1-99. odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. thus, the 405 services the 5, and the 290 services the 90. given a highway number, indicate whether it is a primary or auxiliary highway. if auxiliary, indicate what primary highway it serves. also indicate if the (primary) highway runs north/south or east/west.
