Permute rows within bands If you permute the rows within the same band of a valid Sudoku board, you will obtain another valid board: 1 2 3 4 5 67 8 9 7 8 9 2 3 4 5 6 7 8 9 12 3 4 5 6 2 3 4 5 6 7 8 9 1 5 6 7 8 9 2 3 4 8 9 2 3 4 5 6 7 3 4 5 6 7 8 9 2 6 7 8 92 3 4 5 6 7 8 9 2 3 4 5 Implement a function with the following prototype: void transform_permute_rows (int board[9]I9]); The function should generate a random permutation of the row numbers and swap the rows of the board according to these permutations. Note that some permutations of the {1, 2, . . . , 9} sequence are invalid, because each row can only move within its own band. For example, the permutation {3, 2, 1, 4, 5, 6, 7, 8, 9} illustrated above is valid, while the permutation {4, 2, 3, 1, 5, 6, 7, 8, 9} is invalid. Hint: Create a helper function that generates a random permutation of the {1 . . . n} sequence for any given n. Use permutations generated in this manner to determine how to rearrange the rows of the canonical board.
