We have discussed iterative program to generate all subarrays.In this post, recursive is discussed. Solution is very simple for this problem but since the value of n can be 10^1000000 which cannot be stored in a variable of any data type in c, we need to store each digit in n in a string. Recursion is not free, since, unless function is tail-recursive and compiler knows how to optimize it into iterative implementation, a stack has to be maintained. Hackerrank - Is Fibo Solution.
