Round 1 - Technical 

(3 Questions)

  • Q1. How to check a number is power of 2
  • Ans. 

    To check if a number is a power of 2, we can use bitwise operations.

    • A power of 2 has only one bit set to 1, so we can use the bitwise AND operator to check if the number is a power of 2.

    • If n is a power of 2, then n & (n-1) will be 0.

    • For example, 8 (1000 in binary) is a power of 2, and 8 & 7 (0111 in binary) is 0.

  • Answered by AI
  • Q2. Sort a stack without using another data structure
  • Ans. 

    Sort a stack without using another data structure

    • Use recursion to pop the top element and insert it at the bottom of the remaining stack

    • Repeat until the stack is sorted in ascending order

    • Time complexity: O(n^2), space complexity: O(n) due to recursion

  • Answered by AI

    Check if array has continuous increasing and decreasing values

Interview Preparation Tips

Interview preparation tips for other job seekers - Girls and ladies please don't join this company as it is more into priest kinda,they check your caste,class rather your hardwork it seems. This so called senior recruiter totally flirts with you if you are single,divorce,seperarated and also heard his eyes rolls on always girls upper part,no matter whatever she is wearing. I heard after complaining also higher authorities didn't taken the action. Now you people only imagine how is it safe for a girl to work in that disgusting atmosphere. And in any MNC company if the complain is raised the higher authority should take an action but still they kept him then think what kinda company is this. INDIA HR cgs is worst the worst. They are not giving you secured job,HR are saving there job to close that position and you are bakra,who will be paid with very less salary comparative outside and also you are treated like a dog. Think twice thrice to take the decision.
