Explanation of Solution

Comments in Java:

A comment is used to document the program for better understanding of the program. The compiler treats the comment as a white space and ignores it during execution of the program.

Types of comments:

  • Single line comment
  • Multiline comment
  • Documentation comment.

Single Line comment:

If the compiler encounters a single line comment (//), then it ignores the words up to the end of the line.

Syntax:

Single line comment:

//Java programming

Multiline comment:

If the compiler encounters a multiline comment (/* ...

.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...
