Question 38 The correct statements are: If If Σ □ If If Ø, then Σ* has a subset that is not regular. Ø, then Σ* has a subset that is not context free. Ø, then Σ* has a subset that is not in D. Ø, then Σ* has a subset that is not in SD.
The domain is the set {a, b, c, d, e}. The table below shows the value of two predicates for each of the elements in the domain. Ex: The value of P(c) is false because the truth value in row c and column P is F. PQ a FT bFF CFF d TF e F F Check Next Give exactly one counterexample that shows the proposition VxP(x) is false. Ex: d Give exactly one example that shows the proposition 3xQ(x) is true. 2

The following statements are not saying what the writer probably intendeed, can you figure out why and correct the statements to make them less ambiguous. 1. For set A, its non-empty subsets are B = P(A) \ ∅. 2. Let S be a set and number y, y ∈ |S|
C++ You are given the root node of a binary search tree (BST) and a value to insert into the tree. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Example 1: diagram for example 1 attached Input: root = [4,2,7,1,3], val = 5 Output: [4,2,7,1,3,5] Explanation: Another accepted tree is: Example 2: Input: root = [40,20,60,10,30,50,70], val = 25 Output: [40,20,60,10,30,50,70,null,null,25] Example 3: Input: root = [4,2,7,1,3,null,null,null,null,null,null], val = 5 Output: [4,2,7,1,3,5] Constraints: The number of nodes in the tree will be in the range [0, 104]. -108 <= Node.val <= 108 All the values Node.val are unique. -108 <= val <= 108 It's guaranteed that val does not exist in the original BST.

3.4. An engineer is testing the properties, strength and weight of steel. Suppose he has two fuzzy sets A, defined on a universe of three discrete strengths, {s1, s2, $3}, and B, defined on a universe of three discrete weights, {wi, w2, w3}. Suppose A and B represent a "high-strength steel" and a "near-optimum weight," respectively, as shown, 0.5 0.2 A = $2 $3 0.3 1 B = 0.5 w2 W3 (a) Find the fuzzy relation for the Cartesian product of A and B, that is, find R =A x B. Here, the Cartesian product would represent the strength-to-weight characteristics of a near maximum steel quality. (b) Suppose we introduce another fuzzy set, C, which represents a set of "moder- ately good" steel strengths, say, for example, the following: 0.1 C = S1 0.6 S2 S3 Find the relation between C and B using a Cartesian product, that is, find S = Cx B. (c) Find CoR using max-min composition. (d) Find CoR using max-product composition. (e) Comment on the differences between the results of parts (c) and (d).
