- Below is pseudocode representing the Compute-Opt algorithm: Compute-Opt(j): If j = 0 then Return 0 Else Return max(vj+Compute-Opt(p(j)), Compute-Opt(j − 1)) Endif Memoization of this algorithm does what to its running time? 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_forwardConsider the following recursive algorithm, where // denotes integer division: 3//2 = 1, 5//2 = 2, etc. F(n):if n <= 1: returnF(n//2)for i from 0 to n for j from 0 to n//2 print(i+j) Let function T(n) denote the running time of this algorithm.
