Correct answer will be upvoted else downvoted. Computer science. Positive integer x is called divisor of positive integer y, in case y is distinguishable by x without remaining portion. For instance, 1 is a divisor of 7 and 3 isn't divisor of 8. We gave you an integer d and requested that you track down the littlest positive integer a, to such an extent that a has no less than 4 divisors; contrast between any two divisors of an is essentially d. Input The primary line contains a solitary integer t (1≤t≤3000) — the number of experiments. The primary line of each experiment contains a solitary integer d (1≤d≤10000). Output For each experiment print one integer a — the response for this experiment.
Let L(X) be the statement " X visited London", let P(X) be the statement " X visited Paris" and let N(X) be the statement " X visited New York". Express the statement “None of your friends visited London, Paris and New York.” in terms of C(X), D(X), F(X), quantifiers, and logical connectives where the domain consists of all your friends.
Use De Morgan’s laws to determine whether the two statements are equivalent: ( ~ p ∨ ~ q ) → r , ~ ( p ∧ q ) → r
Discrete Math Answer the following:1. Show that p ∨ (q ∧ r) and (p ∨ q) ∧ (p ∨ r) are logically equivalent. This is the distributive law ofdisjunction over conjunction.2. Show that p ∨ (p ∧ q) are logically equivalent to p.3. Show that p ∧ (p ∨ q) are logically equivalent to p.4. Show that p ∨ p are logically equivalent to p.5. Show that p ∧ q are logically equivalent to p.6. Show that ¬(p → q) and p ∧ ¬q are logically equivalent.
Correct answer will be upvoted else downvoted. Computer science. You are given a grid a comprising of positive integers. It has n lines and m segments. Develop a framework b comprising of positive integers. It ought to have a similar size as a, and the accompanying conditions ought to be met: 1≤bi,j≤106; bi,j is a various of ai,j; the outright worth of the contrast between numbers in any nearby pair of cells (two cells that share a similar side) in b is equivalent to k4 for some integer k≥1 (k isn't really something similar for all sets, it is own for each pair). We can show that the appropriate response consistently exists. Input The primary line contains two integers n and m (2≤n,m≤500). Every one of the accompanying n lines contains m integers. The j-th integer in the I-th line is ai,j (1≤ai,j≤16). Output The output ought to contain n lines each containing m integers. The j-th integer in the I-th line ought to be bi,j.
