Two-dimensional array: A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array. This is useful for storing same type of multiple sets of data in same place. The main advantage is that one-dimensional array can hold only one set of value whereas two-dimensional array can hold multiple sets of data in the form of rows and columns. The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns. The number of elements of an array can be calculated by multiplying the number of rows and number of columns of the array. Example: //Declaring multi-dimensional array double testmarks[5][5]; The above statement is used to create a multidimensional array with “5” rows and “5” columns; the first subscript (that is square bracket) is used to refer the number of rows and the second subscript is used to refer the number of columns. The data type “double” represents that the array will hold only “double” type of data. The “testmarks” array can hold 25 elements (that is 5 × 5 = 25 ).

Program Plan Intro

Two-dimensional array:

A two dimensional array is also called as a multi-dimensional array; a multidimensional array is that all the identical arrays are put together into a single array.

This is useful for storing same type of multiple sets of data in same place.

The main advantage is that one-dimensional array can hold only one set of value whereas two-dimensional array can hold multiple sets of data in the form of rows and columns.

The structure of a multi-dimensional array is lookalike a table (that is combination of rows and columns); it contains same type of columns.

The number of elements of an array can be calculated by multiplying the number of rows and number of columns of the array.

Example:

//Declaring multi-dimensional array

double testmarks[5][5];

The above statement is used to create a multidimensional array with “5” rows and “5” columns; the first subscript (that is square bracket) is used to refer the number of rows and the second subscript is used to refer the number of columns.

The data type “double” represents that the array will hold only “double” type of data.

The “testmarks” array can hold 25 elements (that is 5 × 5 = 25 ).

I need help to solve a simple problem using Grover’s algorithm, where the solution is not necessarily known beforehand. The problem is a 2×2 binary sudoku with two rules: • No column may contain the same value twice. • No row may contain the same value twice. Each square in the sudoku is assigned to a variable as follows: We want to design a quantum circuit that outputs a valid solution to this sudoku. While using Grover’s algorithm for this task is not necessarily practical, the goal is to demonstrate how classical decision problems can be converted into oracles for Grover’s algorithm. Turning the Problem into a Circuit To solve this, an oracle needs to be created that helps identify valid solutions. The first step is to construct a classical function within a quantum circuit that checks whether a given state satisfies the sudoku rules. Since we need to check both columns and rows, there are four conditions to verify: v0 ≠ v1 # Check top row v2 ≠ v3 # Check bottom row…
