NPAV (Net Protector Antivirus) Interview Experience | On-Campus 2021

NPAV generally conducts on-campus pen and paper tests as the first round. All questions were to be solved using C/C++ only. The total time allotted was 1 hr.

Following were the questions asked:

1. Given an input number, print the smallest digit (10marks)

   E.g.

   Input: 519
   Output: 1

2. Print the given number into words(10 marks)

3. Take 16 digit input from the user and print:

   • Multiplication of every 2nd and 3rd digit in the sequence (10marks)

     E.g.

     Input: 1 2 3 4     5 6 7 8    9 10 11 12   13 14 15 16
     Sum = 5 (1+4), Multiplication = 6 (2*3)
     Sum = 13, Multiplication = 42
     Sum = 21, Multiplication = 110
     Sum = 29, Multiplication = 210

4. Take input from the user as name and birthplace and output is as follows: (10marks)

   Input:  

   Name	Birthplace
   Sunil	Mumbai
   Anil	Pune
   Asha	Ahmednagar

   Birthplace	Count	Name
   Mumbai	2	Sunil	Rohit
   Pune	3	Anil	Rohan	Rajesh
   Ahmednagar	1	Asha

5. Given the marks for 10 students for Physics, Chemistry, and Mathematics, calculate the average and find the second highest and the second-lowest average score (10marks)

   Input: 

   	Physics	Chemistry	Maths	Average
   Student1	89	85	91	88
   Student2	45	56	80	60
   Student3	80	95	68	81
   Student4	72	81	65	72
   Student5	63	65	75	67
   Student6	72	82	92	82

   Student8	66	76	56	66
   Student9	90	89	91	90
   Student10	88	86	81	85

   Output: 

   2nd highest average = 88
   2nd lowest average = 60
