Here is a step-by-step solution to the problem:

Step 1: Read the input from the user. The first line of the input is the size of the first list, the second line is the first list of integers, the third line is the size of the second list, and the fourth line is the second list of integers.

Step 2: Convert the lists of integers into sets. A set is a collection of unique elements, so this will remove any duplicate elements from the lists.

Step 3: Use the symmetric_difference method of the set class to find the elements that are not common to both sets. This method returns a new set that contains all items from both sets, but not the items present in both sets.

Step 4: Print the size of the resulting set, which is the count of elements that are not common to both lists.

Here is the Python code that implements these steps:

```python
# Step 1: Read the input from the user
listInput1_size = int(input())
listInput1 = list(map(int, input().split()))
listInput2_size = int(input())
listInput2 = list(map(int, input().split()))

# Step 2: Convert the lists into sets
set1 = set(listInput1)
set2 = set(listInput2)

# Step 3: Find the elements that are not common to both sets
not_common = set1.symmetric_difference(set2)

# Step 4: Print the size of the resulting set
print(len(not_common))
```

You can run this code and provide the input to check the output. For example, if you provide the input from the example in the problem statement, the output will be 12.
