Round duration - 60 minutes
Round difficulty - Medium
The platform was HackerEarth time duration was 1 hour.
1.) 25 MCQs (Both Easy and Gate Level Based)
2.) 1 Coding Question, that needs to be solved in O(logn) time. Program for Fibonacci numbers. The basic idea behind that question is we need to crack the pattern and then based on constraints we need to solve it.
Given an integer 'N', the task is to compute the N'th Fibonacci number using matrix exponentiation. Implement and return the Fibonacci value for the provided 'N'.
Use matrix exponentiation to efficiently compute the Nth Fibonacci number modulo 10^9 + 7.
Implement matrix exponentiation to calculate Fibonacci numbers efficiently.
Use the formula F(n) = F(n-1) + F(n-2) with initial values F(1) = F(2) = 1.
Return the result modulo 10^9 + 7 to handle large Fibonacci numbers.
Optimize the solution to achieve better than O(N) time complexity.
