HR Details: Deepak Nanda

HR Reached out to me on LinkedIn and asked me to share the resume.

HackerRank OA: Sep 12

• Question 1

  Given a list of words, return the no of replacement required in the string, such that no two consecutive characters are same.
  
  Sample Input: [add, boook, break]
  Sample Output: [1, 1, 0]

• Question 2

  A hiker is planning to complete hike to make the world record. Hiker needs to complete his hike in `record` no days and there are multiple trails in the hike. The trails need to be completed in sequential order. Minimize the sum of max trail for each day.
  
  Sample Input 1:
  	n = 6
  	trails[10, 5, 9, 3, 8, 15]
  	record = 2
  Sample Output 1:
  	25
  Explaination:
  	max(10) + max(5, 9, 3, 8, 15) = 25
  
  
  Sample Input 2:
  	n = 5
  	trails[150, 200, 400, 350, 250]
  	record = 3
  Sample Output 2:
  	750
  Explaination:
  	max(150) + max(200), max(400, 350, 250) = 750

Passed all the test cases for both the OA problem. Recieved a call from the HR on Thursday that I'll be having all rounds on Saturday full day - just giving me 48 hours of heads up. I agreed. The recruiter said all the rounds will be elimination round.
