A description of the problem can be found on Hackerrank. Solution. I have given count of numbers n. I will iterate over all numbers from 1 to n I will find index of each iterated number in all elements and then index of index within all elements. I created solution in: Scala; Java; JavaScriptSequence Equation - Hackerrank Challenge - C# Solution Baskar Karunanithi 6th June 2021 Leave a Comment This is the c# solution for the Hackerrank problem - Sequence Equation - Hackerrank Challenge - C# Solution.The Fibonacci sequence is a series of infinite numbers that follow a set pattern. The next number in the sequence is found by adding the two previous numbers in the sequence together. This can be expressed through the equation Fn = Fn-1 + Fn-2, where n represents a number in the sequence and F represents the Fibonacci number value.we get from the sequence, then all we need: to do is use it to solve in reverse the: problem x = f(f(y)) where x is given and: f is our hashmap: Time Complexity: O(n) //We have to iterate every element to build our function list: Space Complexity: O(n) //Our hash map has at most n elements */ import java.io.*; import java.util.*; import java ...But, this solution will take up a lot of time just to compute all the possible combinations, and as your array size starts to grow, you will take more and more time to solve the problem.

We create the function representing the inverse of p(x), and represent it as an array: int [] p_inverse We need to find a ywhere p(p(y)) = x. This equation can be rewritten asThe time complexity of the above iterative solution is O(n) since it contains a loop that repeats n-1 times, but it only takes constant space, in contrast to the recursive approach, which requires O(n) space for recursion (call stack) and exponential time as many subproblems are recalculated repeatedly. We can also improve the time complexity of the recursive approach by saving values that ...Surprisingly, solution of this puzzle is very simple only if you know it already.
