MathJax reference. The current script does 5 things: Slot 4 (t = 3 to t = 4) is free, so schedule it in slot 4. It is also given that every job takes a single unit of time, so the minimum possible deadline for any job is 1. Among all the processes waiting in a waiting queue, the CPU is always assigned to the process having the largest burst time. Tech stack - Python (lightweight libraries, no need to submit a project consisting of 10 files), Beautiful Soup ideally.
