Hiring problem

The term "hire" means "to employ" or "to obtain services for a fee." When you hire someone, you are employing or paying them to perform a certain task for you. A step-by-step method for hiring a new employee is an efficient and successful hiring process in which a business determines its talent needs, recruits from its talent pool, and hires the best-qualified individuals. The hiring problem is a well-known decision-making problem in the analysis of algorithms. The problem is solved by designing an efficient algorithm to choose the best candidate from a list of n candidates.
