I need to see how this code looks. Thank you.
A Sudoku puzzle is a 9x9 grid partially filled with digits from 1 to 9 inclusive. To solve a puzzle, a player must fill the empty squares of the grid so that each row, each column, and each of the nine 3x3 boxes contains every digit from 1 to 9. That is, no row, column, or box contains a duplicate digit. A possible solution is shown below.
Write a program that reads a 9x9 grid of digits and determines whether or not the grid is a solution to a
Sudoku puzzle.
Hint: Use a 2D array to solve this problem.
Hint: Define a separate function which accepts nine integers and returns whether or not they are unique.
Then, repeatedly use this function.
