Explanation of Solution

Problem-solving strategy:

  • It is an idea for solving a problem.
  • Different type of strategies is used to solve the different type of problems.
  • User can use a one or more strategy to solve a single problem.
  • If the user uses many ways to solving problems, then user will determine which strategies they choose and which work good in many conditions.

Types of strategies in problem-solving:

There are three strategies are present in the problem solving:

  • Ask questions:
    • This strategy usually asks questions about the problem or task, and identify the clear information and facts about the problem.
    • This strategy asks the questions such as “when”, “why”, and “where” until the problem or task is clearly and entirely understood.
    • Specify the parts of the task, which are unable to understanding the problems.
  • Looks for familiar things:
    • Some problems have repeatedly happened in computing so it is useful for user identifying the familiar steps that will useful to solve the problem.
    • If the solutions are already existing for the given or same problem, then just repeat the given steps to solve the problem.
      • User needs not to determine the new steps to solve the given problem.
  • Divide and conquer:
    • User can easily handle the problem by dividing the larger problems into smaller ones.
      • It means tasks are split into subtasks. Each subtask is split into sub-subtask if needed.
      • This strategy can be applied repeatedly until each subtask is determined.
        • Example for this strategy is quick sort and binary search algorithm.

(1 point) By dragging statements from the left column to the right column below, give a proof by induction of the following statement: an = = 9" - 1 is a solution to the recurrence relation an = 9an-18 with ao = : 0. The correct proof will use 8 of the statements below. Statements to choose from: Note that a₁ = 9a0 + 8. Now assume that P(n) is true for all n ≥ 0. Your Proof: Put chosen statements in order in this column and press the Submit Answers button. Let P(n) be the predicate, "a = 9″ – 1". απ = 90 − 1 = Note that Let P(n) be the predicate, "an 9" - 1 is a solution to the recurrence relation an = 9an-1 +8 with ao = 0." - Now assume that P(k + 1) is true. Thus P(k) is true for all k. Thus P(k+1) is true. Then ak+1 = 9ak +8, so P(k + 1) is true. = 1 − 1 = 0, as required. Then = 9k — 1. ak Now assume that P(k) is true for an arbitrary integer k ≥ 1. By the recurrence relation, we have ak+1 = ak+1 = = 9ak + 8 = 9(9k − 1) + 8 This simplifies to 9k+19+8 = 9k+1 − 1 Then 9k+1 − 1 = 9(9*…
Given the following request to an AI chatbot, which response is more accurate? (You should use Google to verify that the factual claims in each response are accurate.)   Prompt Is this true? The first recorded use of the phrase "when pigs fly" in print is in a 1616 play by Ben Jonson called "The Devil is an Ass," in which a character says, "When pigs fly, good-night!!" Response   Response A Response B Yes, that's true! The phrase "when pigs fly" indeed appears in Ben Jonson's 1616 play The Devil is an Ass and was said during the second act in a conversation between Fitzdottrel and Pug. The phrase was first used to express skepticism or disbelief, suggesting that something is as unlikely to happen as the fanciful idea of pigs flying. This usage is often cited as one of the earliest instances of the phrase in print.   The claim that the phrase "when pigs fly" was first recorded in Ben Jonson's 1616 play "The Devil is an Ass" is not accurate. There is no evidence from the…
