You may design your own implementation approach, but here are a few constraints.

Your program should read in a list of jobs from a tab-delimited text file named jobs. txt. The format of the text file should have one line for each job, where each line has a job name, a start time and a duration. The job name must be a letter from A-Z. The first job should be named A, and the remaining jobs should be named sequentially following the alphabet, so if there are five jobs, they are named A-E. The arrival times of these jobs should be in order.

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.

Your output should be a graph as shown in the slides. The graph can be text or you can use a graphics package such as JavaFX to draw the graph. For text, you may draw the graph down the page rather than across.

Your program should be able to reproduce the sample shown in the book as well as any similar set of jobs.

Binary search is a classic algorithm in computer science. It often comes up in programming contests and technical interviews. Implementing binary search turns out to be a challenging task, even when you understand the concept. Unless you’re curious or have a specific assignment, you should always leverage existing libraries to do a binary search in Python or any other language.

In this tutorial, you’ll learn how to:

Use the bisect module to do a binary search in Python

Implement a binary search in Python both recursively and iteratively

Recognize and fix defects in a binary search Python implementation

Analyze the time-space complexity of the binary search algorithm

Search even faster than binary search
