Second order Spada numbers are well established in the insurance industry. Formally they are defined by the recurrence: Si={Si−1 %( Si−2+1) :i≥ 2 , 1:i=0 ,7 :i=1} Give an O(n) time algorithm to compute the n-th Second order Spada number
The number of operations executed by algorithms A is 5n^2 and by algorithm B is 30n^3. Determine n0 such that B is better than A for all n > n0.
An integer n is called k-perfect if u(n) =kn. Note that a perfect number is 2-perfect. Showthat 120 = 23 • 3 · 5 is 3-perfect.

- Suppose that you have five different algorithms (A. B. C. Dand E) for solving a problem. To solve a problem of size n, the number of operations used by each algorithm is as follows.

- Question: Design an algorithm for this problem with worst-case runtime of O(n).arrow_forwardA computer science student designed two candidate algorithms for a problem while working on his part-time job The time complexity of these two algorithms are T,(n) = 3 n logn and T2(n) = n6/5 a) Which algorithm is better? Why? b) If we run both algorithms at the same time with an input size of 105, which algorithm produces results faster than the other one? Why?arrow_forwardA certain recursive algorithm takes an input list of n elements. Divides the list into Vn sub-lists, each with yn elements. Recursively solves each of these yn smaller sub- instances. Then spends an additional 0(n) time to combine the solutions of these sub- instances to obtain the solution of the main instance. As a base case, if the size of the input list is at most a specified positive constant, then the algorithm solves such a small instance directly in 0(1) time. a) Express the recurrence relation that governs T(n), the time complexity of this algorithm. b) Derive the solution to this recurrence relation: T(n) = 0(?).

Group of answer choices It reduces the running time from exponential to linear. It reduces the running time from O(n2) to O(n). It reduces the running time from exponential to O(n log n). It doesn't significantly reduce the running time, but it enables the algorithm to utilize less space.arrow_forward
