To solve this problem, we need to follow these steps:

1. First, we need to define a function to calculate the cost of an array. This function will iterate over each element in the array and calculate the cost of that element. The cost of an element is the minimum number of operations to convert it to 0 or 1. In each operation, we can take any prime factor of the remaining value and subtract it from the element.

2. To calculate the cost of an element, we can use the following approach: If the element is 0 or 1, its cost is 0. If the element is a prime number, its cost is 1. If the element is a composite number, its cost is the smallest prime factor of the element.

3. After calculating the cost of each element in the array, we sum up all the costs to get the total cost of the array.

4. We then calculate the cost of both arrays, arr1 and arr2.

5. Finally, we compare the cost of arr1 and arr2. If the cost of arr1 is less than or equal to the cost of arr2, we return 1. Otherwise, we return 0.

Here is a Python code snippet that implements the above steps:

```python
def cost(arr):
def smallest_prime(n):
if n

Here is a Python code snippet that implements the above steps:

```python
def cost(arr):
    def smallest_prime(n):
        if n <= 1:
            return 0
        if n <= 3:
            return n
        if n % 2 == 0:
            return 2
        i = 3
        while i * i <= n:
            if n % i == 0:
                return i
            i += 2
        return n

return sum(smallest_prime(x) for x in arr)

def compare_cost(arr1, arr2):
    return 1 if cost(arr1) <= cost(arr2) else 0
```

In the given example, the cost of arr1 is 1 and the cost of arr2 is 0. So the function compare_cost returns 0.
