Write a C++ function, bool ok(int q[]), which takes an array q and returns true if the array represents a valid configuration of the eight queens and returns false otherwise.
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).

A triple (x, y, z) of positive integers is pythagorean if x2 + y2 = z2. Using the functions studied in class, define a function pyth which returns the list of all pythagorean triples whose components are at most a given limit. For example, function call pyth(10) should return [(3, 4, 5), (4, 3, 5), (6, 8, 10), (8, 6, 10)]. [Hint: One way to do this is to construct a list of all triples (use unfold to create a list of integers, and then a for-comprehension to create a list of all triples), and then select the pythagorean ones. def unfold[A, S](z: S)(f: S => Option[(A, S)]): LazyList[A] = f(z) match { case Some((h, s)) => h #:: unfold(s)(f) case None => LazyList() } code in scala
