- Python question Analysis: Computational Complexity (Q14-15) In this section, you are asked to analyse the worst-case computational time complexity of Python functions. Always identify the order of growth in the tightest and simplest possible form using big-O notation, e.g., write O(n) instead of O(2n+n/2). Question 14 (Complexity 1) State the overall worst-case time complexity of the below function and provide a short explanation of your answer. The function accepts an integer n as input. def mystery(n): num = 1 count = 0 while num < n: num = num*2 count += 1 return count Question 15 (Complexity 2) State the overall worst-case time complexity of the below function and provide a short explanation of your answer. The function is supposed to return a list, res, containing the duplicated elements in the given list , lst, of size n. Analyse the function in terms of the length of the list, n. def duplicate_values(lst): res = [] for i in range(len(lst)):…Exercise 1: The number of combinations CR represents the number of subsets of cardi- nal p of a set of cardinal n. It is defined by C = 1 if p = 0 or if p = n, and by C = C+ C in the general case. An interesting property to nxC calculate the combinations is: C : Write the recursive function to solve this problem.Python only* Use recursive function*. Define colorListCircles with 2 parameters Use def to define colorListCircles with 2 parameters The colorListCircles function must draw concentric circles using colors from a list. It has two parameters: the first specifies the radius of the largest circle, and the second is a list of colors. The number of concentric circles drawn is the length of the list, and these circles are colored, from largest to smallest, by the colors in the list from first to last. When viewed as nested rings, all rings should have the same thickness. If the list is empty, nothing should be drawn. We will test both how many circles are drawn as well as whether the correct circles are drawn in the correct order, you may not use any loops and you must use recursion. Also, you will still need to use drawDot. For full credit, your function should call drawDot in only one place, and should only contain one recursive call. Do not use any kind of loop Within the definition…

For example, for the array below, the function largest should return 22,which is the largest value in the array. You can assume there are no more 20 integers in thearray. Think of how to formulate the recurrence relation in this problem yourself.

- c++ computer language randomly generates integers in the interval [1,10] a.1+rand()%11 b.rand()%11 c.rand()%10 d.1+rand()%108. Ackerman's Function Ackermann's Function is a recursive mathematical algorithm that can be used to test how well a system optimizes its performance of recursion. Design a function ackermann(m, n), which solves Ackermann's function. Use the following logic in your function: If m = 0 then return n + 1 If n = 0 then return ackermann(m-1,1) Otherwise, return ackermann(m-1,ackermann(m,n-1)) Once you've designed yyour function, test it by calling it with small values for m and n. Use Python.Artificial Intelligence (Part - 1) ==================== The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. (1) Propose a state representation for the problem?
