Suppose n e Z. (That is, throughout this question, n is an arbitrary integer; you cannot pick a particular value for n to be.) (a) Consider the following proposition, which we'll call P: If 7n + 5 is odd, then n is even. What is the contrapositive of P? (b) Prove (using a direct proof) that the contrapositive of P is true. (You do not need to write English sentences as in the homework solutions.)

3. Prof. Poirot needs help. He has a regular expression r and wants to write a regular expression s that generates the the complement of L(r). Can you give him an algorithm for this task? Write it in precise and clear English.
Give a recursive definition for the set of all strings of a’s and b’s that begins with an a and ends in a b. Say, S = { ab, aab, abb, aaab, aabb, abbb, abab..} Let S be the set of all strings of a’s and b’s that begins with a and ends in a b. The recursive definition is as follows – Base:... Recursion: If u ∈ S, then... Restriction: There are no elements of S other than those obtained from the base and recursion of S.
c) What is the inductive hypothesis of a proof that P(n) is true for all positive integers n? d) What do you need to prove in the inductive step of a de proof that P(n) is true for all positive integers n? e) Complete the inductive step of a proof that P(n) is true for all positive integers n, identifying where you use the inductive hypothesis.
Correct answer will be upvoted else downvoted. Computer science. All arbitrary choices that are made during the title are made similarly plausible and autonomously. For instance, assuming n=4, a=[1,2,4,3], one of the choices for the game (there could be different choices) is: during the main game, the first and fourth players were chosen. The fourth player has more tokens, so he takes the main player's tokens. Presently a=[0,2,4,4]; during the subsequent game, the fourth and third players were chosen. They have similar number of tokens, yet arbitrarily, the third player is the champ. Presently a=[0,2,8,0]; during the third game, the second and third players were chosen. The third player has more tokens, so he requires the second player's tokens. Presently a=[0,0,10,0]; the third player is proclaimed the victor of the title. Title champs will get customized prizes. Consequently, the adjudicators need to know ahead of time which players get an opportunity of winning,…
The three integers n, I and j, with I and j being between 1 and 2n, are the prerequisites to the issue. You have a board of squares that is 2n by 2n squares. Each tile has an adequate amount of pieces and the desired form. With the exception of the solitary square at position I j, you must cover every 2n 2n tile on the board by placing nonoverlapping tiles. Provide a recursive method for this issue where you lay one tile on your own and then enlist the aid of four buddies. a case is a phrase, right?
Correct answer will be upvoted else downvoted. Computer science. Koyomi has recently gotten the three brief strings from the challenge coordinators. Assist her with composing a substantial novel for the challenge. A string a will be an aftereffect of a string b if a can be acquired from b by erasure of a few (perhaps, zero) characters. Input The principal line contains a solitary integer t (1≤t≤104) — the number of experiments. The principal line of each experiment contains a solitary integer n (1≤n≤105). Every one of the accompanying three lines contains a bitstring of length 2n. It is ensured that these three strings are pairwise unmistakable. It is ensured that the amount of n across all experiments doesn't surpass 105. Output For each experiment, print a solitary line containing a bitstring of length at most 3n that has somewhere around two of the given bitstrings as aftereffects. It very well may be demonstrated that under the imperatives of the…
IN VISUAL BASIC, solve Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
Below are some statements; the domain of each is the set of all integers. For symbolic statements, thenegation symbol (¬) must not apear in your answer. For English statements, don’t use “It is not the casethat” or just the word “not” to form the negation.For each one, state whether the statement is TRUE, FALSE, or CAN’T BE DETERMINED. For all that onesthat are TRUE or FALSE, state the negation:1.∃n(nis even)2.∀a∀b(3a≥2b)3.∀a∃b(ab= 1)
Let ∑={a,b} and T be the set of words in ∑* that have no consecutive a’s (i.e. there cannot be 2 or more a’s in a row). (a) Give a recursive definition for the set T. (b) Use your recursive definition to show that the string “abbaba” is in T. (c) Is your recursive definition uniquely determined? Explain why or why not.
Can you help me with this code because this is a little difficult for me:question that i need help with:The Lights Out puzzle consists of an m x n grid of lights, each of which has two states: on and off. The goal of the puzzle is to turn all the lights off, with the caveat that whenever a light is toggled, its neighbors above, below, to the left, and to the right will be toggled as well. If a light along the edge of the board is toggled, then fewer than four other lights will be affected, as the missing neighbors will beignored. In this section, you will investigate the behavior of Lights Out puzzles of various sizes by implementing a LightsOutPuzzle class task: A natural representation for this puzzle is a two-dimensional list of Boolean values, where True corresponds to the on state and False corresponds to the off state. In the LightsOutPuzzle class, write an initialization method __init__(self, board) that stores an input board of this form for future use. Also write a method…
