Longest Job First (LJF) CPU Scheduling Algorithm
Longest Job First (LJF) is a CPU scheduling algorithm that prioritizes processes based on their burst time. In LJF, the processes with the largest burst time are given priority over the shorter ones.

To implement the LJF algorithm, processes are sorted in the ready queue based on their burst times in descending order. The process with the largest burst time among all the processes that have arrived until that time is ...
