Sum of divisors from 1 to n using recursion
WebWhich of the following recursive formula can be used to find the factorial of a number? A.fact (n) = n * fact (n) B. fact (n) = n * fact (n+1) C. fact (n) = n * fact (n-1) D.fact (n) = n * fact (1) Suppose the first fibonnaci number is 0 and the second is 1. What is the sixth fibonnaci number? A.5 B. 6 C. 7 D.8 WebThen, our running time is similar to the algorithm itself. Since the base cases run in constant time and each recursive case takes T (n − 1) and T (n − 2), respectively, we have: T (n) ≤ O(1) + T (n − 1) + T (n − 2) So T (n) ≥ Fn; that is, our running time takes at least as much time as the Fibonacci number itself!

Web28 Mar 2024 · Naive approach: A simple solution is to store all of the divisors of A and B then iterate over all the divisors of A and B pairwise to find the pair of elements which are co-prime. Efficient approach: If an integer d divides gcd(a, b) then gcd(a / d, b / d) = gcd(a, b) / d.More formally, if num = gcd(a, b) then gcd(a / num, b / num) = 1 i.e. (a / num) and (b / …
