WebOct 7, 2024 · The idea is to modify the recursive step as follows. If n is an even number, then we can write n as n = 2k. 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. Based on this observation, we can write this recursive function: WebMar 16, 2024 · In general, the time complexity of a recursive function depends on the number of recursive calls and the size of the input at each level of the recursion.

WebOct 20, 2024 · We know that the recursive equation for Fibonacci is = + +. What this means is, the time taken to calculate fib (n) is equal to the sum of time taken to calculate fib (n-1) and fib (n-2). This also includes the constant time to perform the previous addition. WebApr 26, 2011 · That would be the solution to n/2^I = 1 -> I = Log2 (n). Plant it in the equation for Ti and you get: TI (n) = 2^log2 (n)*T (n/2^log2 (n)) + log2 (n) = n*1+log2 (n) = n + log2 (n) and you get T (n) = O (n + log2 (n) (just like @bdares said) = O (n) (just like @bdares said) Share Improve this answer Follow edited Oct 22, 2011 at 6:39 WebFormulating the recurrences is straightforward, but solving them is sometimes more difficult.
