- Write a C program using embedded assembler with a function to convert a digit (0 – 15) to the corresponding ASCII character representing the value in hexadecimal. For numbers 0 – 9, the output will be the characters '0' – '9', for numbers 10 – 15 the characters 'A' – 'F'. The entire core of the program must be written in symbolic instruction language; arrays may not be used. You may only use C to print the result. Tip: This piece of C program will do the same thing: character = number < 10 ? number + '0' : number + 55; As a basis, you can use this program again , which increments a variable. Just replace the INC instruction with ADD and add a test (CMP) with some conditional jump.arrow_forwardAnswer 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).arrow_forward.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…arrow_forward
