What are the mechanics in sudoku?
The mechanics involved in sudoku follow the principal, that any 3x3 grid can be filled with the numbers 1-9, every row can have 1-9, and every column can have 1-9, to eventually have a complete 9x9 grid filled with the numbers 1-9, where no numbers in any row, column, or 3x3 grid have two of the same number

6,670,903,752,021,072,936,960 , or 6.67*10^21.
What is the maximum possible number of givens in a standard 9X9 Sudoku grid that does not render a unique solution?
A Sudoku can have a non-unique solution with only 4 empty cells. Here's an example: 003496758 587132469 694875213 008763945 946581327 375924186 761259834 852347691 439618572 If the first 2 cells are filled with 1,2 the 2 in row 4 must be 2,1, and vice-versa. So there can be up to 77 givens in a 9x9 sudoku without a unique solution.

What is the sudoku solver c plus plus code?
The code is below and i should also explain the algorithm. Well, What we are doing here is that we already defined the size to be 9x9 sudoku and are getting values using loops. All the empty spots are given UNASSIGNED value. Then we have functions to tell that if it is safe to put a value in the empty box by calculation and according to the rules of Sudoku it checks for is there any other some number horizontally and vertically and do the sum of the row and column is less than or equal to required or not. If the functions returns true then the program puts the value there.#include #define UNASSIGNED 0#define N 9bool FindUnassignedLocation(int grid[N][N], int &row, int &col);bool isSafe(int grid[N][N], int row, int col, int num);bool SolveSudoku(int grid[N][N]){int row, col;if (!FindUnassignedLocation(grid, row, col))return true; // success!for (int num = 1; num
