WebThe number of recursive function calls follows the Fibonacci sequence. The closed form for the Fibonacci sequence is exponential in n. In fact, it is O(((1+sqrt{5})/2)^n), which is about O(1.6^n). It is simple to calculate by diagraming function calls. Simply add the function calls for each value of n and look at how the number grows. WebApr 13, 2024 · No. of function calls made during recursion. Time is taken to execute a single function call. Thus time complexity of the above code is O(n) * O(1) ~= O(n): As "n" is no. …

Then m^n = m^(2k) = (m^k)^2. If n is an odd number, then we can write n as n = 2k + 1. Then m^n = m^(2k+1) = m * m^(2k) = m* (m^k)^2.
