    Input:

    ...
  • Ans. 

    Calculate the Nth Fibonacci number efficiently using dynamic programming.

    • Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.

    • Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).

    • Ensure the input N is within the constraints 1 <= N <= 10000.

Skill Tips: Infosys Internship program is structured very similar to Infosys Foundation Program. In both programs, the course is divided into two parts -
Generic Training and Stream Training. Generic Training will be based on Computer Science' fundamental subjects like OOPs using Java, RDBMS using Oracle, Software Engineering, Internetworking and Operating Systems. Stream specific training will be based on a certain technology like J2EE, DOT NET, Mainframe, SAP etc.

If you're unable to pass the internship program, you can join Infosys as a Systems Engineer trainee after you complete your engineering course and can undergo Infosys Foundation Program. Accommodation is free while going through internship program. You need to pay for food and for other amenities like Gym and Sports facilities.
The monthly stipend during internship program is INR 8000. Advantages for opting internship program is Infosys internship program would help you to undergo the initial training course while joining Infosys. So, if you successfully complete the internship program, you need not to attend the Foundation training in Infosys. So, when you rejoin infosys after completing your b.tech course, you would join as an employee, not as a trainee. It will help you get into production much advanced to other people who go through Foundation Program. After you complete your engineering course Infosys will communicate you with a date to rejoin the organization.
After you complete your internship and get posting location. When you rejoin Infosys, you have to report to that office only. Need not to come to Mysore or Mangalore again for reporting.
Once you join for internship program, you have to sign a bond and if you do not opt to rejoin Infosys then you need to consider the consequences as per the rules written in the bond like paying some amount.
One advantage of successfully clearing internship program is that you need not to go through Foundation program in Infosys. Both have equal weightage in Infosys. Scope of learning is same in both type of training.
