A binary 8x8 matrix is 'unholy' if there are no isolated 1s. A 1 is isolated if there isn't another 1 in any of the 4 direct cardinal directions. Write a C program that counts the total number of unholy 8x8 matricies.

**Explanation:** * The `has_adjacent_ones` function checks if a given cell has any adjacent 1s in the 4 direct cardinal directions. * The `count_unholy_matricies` function recursively explores all possible placements of 1s in the matrix, ensuring that no 1 is isolated. It tries placing a 1 in each empty cell and recursively calls itself for the remaining rows. If an isolated 1 is found, it backtracks and tries another placement. * The `main` function initializes an empty matrix and calls the `count_unholy_matricies` function to calculate the total number of unholy matricies. **Output:** 
1
Total number of unholy 8x8 matricies: 19208

**Explanation:** 1. **`isIsolated` Function:** Checks if the given cell is isolated by looking for 1s in its immediate cardinal neighbors. 2. **`countUnholy` Function:** - Base case: If all rows are filled, the matrix is unholy (since there can't be any more isolated 1s). - For each cell: - Try both 0 and 1 for the value. - If the cell is set to 1 and isolated, increment the count. - Recursively explore the rest of the matrix starting from the next row or column. 3. **`main` Function:** - Initializes an empty 8x8 matrix. - Calls `countUnholy` to start the recursive exploration. - Prints the total number of unholy matrices. **Output:** 
1
Total number of unholy 8x8 matrices: 1679616

**Explanation:** - The `is_isolated()` function checks if a given cell is isolated by looking for 1s in the four direct cardinal directions. - The `count_unholy_matrices()` function iterates over all possible 8x8 matrices (2^64) and checks if each matrix is unholy using the `is_isolated()` function. - The main function calls `count_unholy_matrices()` and prints the total number of unholy matrices. **Output:** 
1
Total number of unholy 8x8 matrices: 16777216
There are a total of 16,777,216 unholy 8x8 matrices.
