Chapter 5, Problem 27P
Program Plan Intro

Recursive method with calling signature

Program plan:

  • Create a class FindFile.
    • In find() method,
    • Check whether the list is not “null”. If yes,
      • The for loop executes until the list. If yes,
        • Check whether the directory is there in the list. If yes,
          • Call recursively find() method to find path from the file name in the list.
        • Otherwise, check whether the given file name is equal to the filename in the list. If yes,
          • Fetch the parents file of the given file name and then display it.
    • In main() method,
      • Create an object for FindFile class.
      • Read the input file name and directory name from the user.
      • Call the find() method to find the path of the file name and then display it.

Answer the question fully and accurately by providing the required files(Java Code, Two output files and written answers to questions 1-3 in a word document)meaning question 1 to 3 also provide correct answers for those questions.(note: this quetion is not graded).
.NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…
