Job Sequencing with Deadline will occur in following  steps:

Step 1: Create an array whose size is equal is to the maximum deadline given.This will take constant time.

Step 2: Sort out the jobs in descending order of their profits. Best complexity: O(nlogn)

Step 3: Take the job one by one(O(n)) and find the particular slots to fix that job based on greedy analysis, worst case, slot will found in O(n) time. total complexity: O(n^2)

so overall complexity: O(1) + O(nlogn) +O(n^2) = O(n^2)...

Algorithm Madeeasy Workbook
As we have to select maximal set of “non overlapping” activities. So like job scheduling algo of greedy we can solve it. So according to that complexity must be O(n logn). But ans is (b). Anyone please explain.
