Question
You are given jobs and need to schedule them. Each job is of one time unit duration but provide
different profits for the company. Consider the sort as shown below Total Jobs TJ done and the
Maximum Profit MP.
1 Sort the jobs based on decreasing order of profit.
2 Create two variables, TJ = 0, MP = 0.
3 Find the maximum deadline among all the jobs.
4 Initialise a set storing all the jobs in decreasing order of profit.
5 Iterate through the jobs and perform the following:
i. If the set is empty or the deadline of the current job is less than the last element of the set,
ignore the job.
ii. Else, apply binary search dividing by deadline ≤ or> i. Find the nearest Slot i, such that
i < deadline and add the profit.
iii. Increment total jobs by 1 and remove the ith element from the set.
6 Return the maximum profit.
'Item number', complete by, profit
[['a', 3, 35], # Job Array
['b', 4, 30],
['c', 4, 25],
['d', 2, 20],
['e', 3, 15],
['f', 1, 12],
['g', 2, 5]]
Maximum profit sequence of jobs:
d cab
Profit 110
e.g.

Answer the following questions on this problem (Do not provide code)
(a) Do we need to do the initial sort of the jobs array? Why or why not.
(b) What will be the efficiency of this algorithm by calculating from the steps of the pseudo code?
Explain how you calculated this.
