We implement the Shortest Job Duration First algorithm using the Greedy technique by selecting the shortest job from the array. To always select the shortest job first we sort the job duration array in ascending order based on their duration.
Once the jobs are sorted, we iterate through each job in the sorted list. For each iteration the waiting time is the sum of the total time taken by all previous jobs. We calculate the waiting time for each job and update the total time taken by adding the duration of the current job to the total waiting time.
