(S× T) n (Tx S) – (S × S) = Ø. Consider the proof that supposes (Sx T) (T× S) - (S × S) ‡ Ø and wants to show that : [x = (S× S) x (S × S)]. True or False: This is a valid proof approach that would prove the claim. (This is not asking whether this is an actual proof of the result. It's asking whether this general, high-level approach would suffice to prove the result.)

Order 7 of the following sentences so that they prove the following statement by contrapositive: For any integers m and n, if 3 + mn, then 3 + m. Proof by contrapositive of the statement (in order): Choose from this list of sentences Since 3 m, there exists an integer k such that m = 3k Since k and n are integers and integers are closed under multiplication kn must be an integer 3|m Since 31mn, there exists an integer k such that mn = 3k It follows that, mn= 3kn = 3(kn) Let m and n be integers and 3 mn Since mn equals 3 times an integer 3 mn Let m and n be integers and 3 m
1: Given a fixed integer B (B ≥ 2), we demonstrate that any integer N (N ≥ 0) can bewritten in a unique way in the form of the sum of p+1 terms as follows:N = a0 + a1×B + a2×B2 + … + ap×Bpwhere all ai, for 0 ≤ i ≤ p, are integer such that 0 ≤ ai ≤ B-1.The notation apap-1…a0 is called the representation of N in base B. Notice that a0 is theremainder of the Euclidean division of N by B. If Q is the quotient, a1 is the remainder of theEuclidean division of Q by B, etc.1. Write an algorithm that generates the representation of N in base B. 22. Compute the time complexity of your algorithm.
Correct answer will be upvoted else downvoted. Computer science. lamp can be coordinated to enlighten either a few lights to the left or a few lamps to the right. In the event that the I-th lamp is gone to one side, it enlightens all such lights j that j∈[i−pi,i−1]. Also, in case it is gone to one side, it enlightens all such lamps j that j∈[i+1,i+pi]. You will probably pick a course for every light so every lamp is enlightened by undoubtedly another lamp, or report that it is incomprehensible. Input The primary line contains one integer t (1≤t≤10000) — the number of experiments. Each experiment comprises of two lines. The primary line contains one integer n (2≤n≤3⋅105) — the number of lamps. The subsequent line contains n integers p1,p2,… ,pn (0≤pi≤n) — the force of the I-th lamp. The amount of n over all experiments doesn't surpass 3⋅105. Output For each experiment, print the appropriate response as follows: In case it is feasible to coordinate all lamps…
Note: For all integers k,n it is true that kn, k+n, and k-n are integers. An integer k is even if and only if there exists an integer r such that k=2r. An integer k is odd if and only if there exists an integer r such that k=2r+1. For every integer k it is true that if k is even then k is not odd. For every integer k it is true that if k is odd then k is not even. For every integer k it is true that if k is not even then k is odd. For every integer k it is true that if k is not odd then k is even. If P then Q means the same thing as P → Q (P implies Q). 3. Consider the argument form pvr .. p→r Is this argument form valid? Prove that your answer is correct. 4. Prove that for every integer d, if d³ is odd then d is odd.

If five integers are chosen from the set {1, 2, 3, 4, 5, 6, 7, 8}, must there be at least two integers with the property that the larger minus the smaller is 2? Write an answer that would convince a good but skeptical fellow student who has learned the statement of the pigeonhole principle but not seen an application like this one. Describe the pigeons, the pigeonholes, and how the pigeons get to the pigeonholes.

Based on the pumping lemma, if L is regular, then 3k > 1 (strings w E L, where |w|> k (3x, y,z (w = xyz, |xy| ≤k, ye, and Vq ≥ 0 (xyz is in L)))). The correct statements are: For L = ab*ab, let k = 2 and every string w in L with |w|> k must be pumpable. For L = ab* ab, let k = 3 and every string w in L with |w|> k must be pumpable. For L = ab*ab, let k = 4 and every string w in L with |w|> k must be pumpable. For L = ab* ab, let k = 5 and every string w in L with |w| >k must be pumpable.
7. For n 2 1, in how many out of the n! permutations T = (T(1), 7(2),..., 7 (n)) of the numbers {1, 2, ..., n} the value of 7(i) is either i – 1, or i, or i +1 for all 1 < i < n? Example: The permutation (21354) follows the rules while the permutation (21534) does not because 7(3) = 5. Hint: Find the answer for small n by checking all the permutations and then find the recursive formula depending on the possible values for 1(n).
