Explanation of Solution
The program errors and the corrections are explained in the in-lined comments:
#include <iostream>
using namespace std;
int main()
{
//speed is a int pointer which is declared and
//memory allocated
int *speed = new int; //Line 1
//double pointers are declared
double *travelTime; //Line 2
double *distance; //Line 3
//value of 65 is stored in the memory allocated
//pointed to by speed using address of operator
//& which is wrong
///&speed = 65; //Line 4
//correct line is
*speed = 65;
//value is attempted to be stored at a memory location
//which is pointed to by travelTime but actually
//no memory has yet been allocated so memory

- Please answer Java OOP Questions.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_forwardNeed help with this in python!arrow_forward
