In C++oldmanSea.txt contains:He was an old man who fished alone in a skiff in the Gulf of Mexico Stream and he had goneeighty-four days now without taking a fish . In the first forty days a boy had been with him . But after forty days without a fish the boy’s parents had told him that the old man was now definitely and finally salao , which is the worst form of unlucky , and the boy had gone at their orders in another boat which caught three good fish the first week . It made the boy sad to see the old man come in each day with his skiff empty and he always wentdown to help him carry either the coiled lines or the gaff and harpoon and the sail that was furled around the mast . The sail was patched with flour sacks and, furled , it looked like the flag of permanent defeat .The old man was thin and gaunt with deep wrinkles in the back of his neck . The brown blotches of the benevolent skin cancer the sun brings from its reflection on the tropic sea were on his cheeks .
(Fibonacci) The Fibonacci series0, 1, 1, 2, 3, 5, 8, 13, 21, …begins with the terms 0 and 1 and has the property that each succeeding term is the sum of the twopreceding terms. a) Write a nonrecursive function fibonacci(n) that calculates the nth Fibonaccinumber. Use unsigned int for the function’s parameter and unsigned long long int for its returntype. b) Determine the largest Fibonacci number that can be printed on your system.
Adt. If possitble, rethace the answe (10)/(21)+(1)/(9) Please give proper explanation and typed answer only.
Problem 5: Functions and Sets Let Σ denote a finite alphabet, Σ* denote all words over that alphabet, and L denote the function that maps a string to its length, i.e. L : Σ* → N (where N denotes the natural numbers) [a] Is L partial, total, or both? [b] Is L one-to-one? onto? a bijection? [c] How many words in Σ* have length n? [d] How many words in Σ* have length ≤ n [e] Explain whether Σ* is finite, countable, or uncountable. [f] Explain whether P(Σ*) - the set of all subsets over Σ* - is finite, countable, or uncountable. Hint: how is this related to the real numbers in [0, 1).
Show that the given argument is either valid or invalid using resolution. Either I love math or I’m obsessed with it. If I love math, then I will major in it. I am not majoring in math, therefore I am obsessed with math.

Warm-up Exercise Answer and study the questions below. Final Exam is on May 3, 2021. 1. Find the domain and range of the following function f. It assigns toeach string of bits (that is, of 0s and 1s) the number equal to twice of thenumber of zeros in that string. For example f(011001010101010) = 16. 2. Determine whether or not the function f : Z × Z ! Z is onto, if f((m, n)) =m-n. 3. Give an explicit formula for a function from the set of all integers tothe set of positive integers that is onto but is not one-to-one.
a) Given the following non-tail recursive function for determining whether a given number is even or not: (ns core-clj.core (:gen-class)) (defn even-num? [n] (if (= n 0) true (not (even-num? (dec n))))) (defn -main [] (println) (even-num? 8))) Rewrite the above clojure function (even-num?) so it can enforce the TCO condition: (b) Use the built-in higher ordered functions like (filter, map, take or reduce) to filter out the first three even numbers in given list like (4 7 9 6 19 8 21). Note: you need to call the even-num? function given in (a).
3. Please Help me to solve the following all the subparts perfectly on word: PS: You just need to show the prove or disprove (for a) and show the prove or show if it is true (for b).
5 A. Let * be a new logical connective such that p * q does not hold if and only if p and q are either both false or both true. (i) Write down the truth table for p * q (ii) Write down the truth table for (p * p) * (q * q). (iii) Does the table in (b) coincide with a table in *Truth table available on the given image* (By "Coincide" we mean that the respective columns of T and F values are the same) B. Construct a formula in CNF based on each of the following truth tables: *Truth table available on the given image* C. Compute CNF (NNF ( IMPL_FREE ¬(p → ( ¬ (q ∧ ( ¬p → q))))))
