Problem 7 [ I: 18 l: Ancestors How many ancestors does a person have, in total, among theprevious n generations of their relatives? (Assume every person has two parents, a person is theirown ancestor and that one's parents comprise the n = 1 generation)Explain the relationship between your response and an unsigned binary number, what doeseach digit represent in the context of counting ancestors?

Ans a) 2(n+1) - 1 The main point to note here is that each person has exactly two parents,…

CODING QUESTION. Euler's totient function, also known as phi-function ϕ(n),counts the number of integers between 1 and n inclusive,which are coprime to n.(Two numbers are coprime if their greatest common divisor (GCD) equals 1)."""def euler_totient(n): """Euler's totient function or Phi function. Time Complexity: O(sqrt(n)).""" result = n.
1. (a)The objective is to shuffle a given array of n different elements. You would like to compare various shuffling algorithms and select the best of them. What does it mean: “the best shuffling algorithm”? What is a requirement for the perfect shuffling algorithm? (b) Is the Fisher-Yates Shuffle the perfect shuffling algorithm? Present a formal mathematical proof that this algorithm meets (or does not meet) the requirement given in (a). (c) Evaluate empirically performance of the Fisher-Yates Shuffle for selected numerical values of n. Propose your evaluation criteria and explain your evaluation methodology. Report your observations and conclusions.

This is a practice question from my Data Structures course: h(n) = {1 if n = 1; 3 × h(n - 1) - 1 otherwise} Rewrite h(n) using an explicit formula that is not recursive (i.e., succinctly express h(n) as a polynomial/exponential function of n). Also, prove the correctness of your expression using mathematical induction. Please explain how to do this (as opposed to simply providing the answer). Thank you for your assistance.

Q5
Use recursive functions only Python only** onlyAU - Given an RNA sequence, returns a new sequence consisting of only the 'A' and 'U' bases from the original sequence with the 'C' and 'G' bases removed. Define onlyAU with 1 parameter Use def to define onlyAU with 1 parameter Do not use any kind of loop Within the definition of onlyAU with 1 parameter, do not use any kind of loop. Use a return statement Within the definition of onlyAU with 1 parameter, use return _ in at least one place. Call onlyAU Within the definition of onlyAU with 1 parameter, call onlyAU in at least one place.
