### Instructions: You are an expert Python programmer. You will be given a question (problem specification) and will generate a correct Python program that matches the specification and passes all tests. You will NOT return anything except for the program.
### Question:
An ant is on a boundary. It sometimes goes left and sometimes right.
You are given an array of non-zero integers nums. The ant starts reading nums from the first element of it to its end. At each step, it moves according to the value of the current element:

If nums[i] < 0, it moves left by -nums[i] units.
If nums[i] > 0, it moves right by nums[i] units.

Return the number of times the ant returns to the boundary.
Notes:

There is an infinite space on both sides of the boundary.
We check whether the ant is on the boundary only after it has moved |nums[i]| units. In other words, if the ant crosses the boundary during its movement, it does not count.


Example 1:

Input: nums = [2,3,-5]
Output: 1
Explanation: After the first step, the ant is 2 steps to the right of the boundary.
After the second step, the ant is 5 steps to the right of the boundary.
After the third step, the ant is on the boundary.
So the answer is 1.

Example 2:

Input: nums = [3,2,-3,-4]
Output: 0
Explanation: After the first step, the ant is 3 steps to the right of the boundary.
After the second step, the ant is 5 steps to the right of the boundary.
After the third step, the ant is 2 steps to the right of the boundary.
After the fourth step, the ant is 2 steps to the left of the boundary.
The ant never returned to the boundary, so the answer is 0.


Constraints:

1 <= nums.length <= 100
-10 <= nums[i] <= 10
nums[i] != 0

### Format: You will use the following starter code to write the solution to the problem and enclose your code within delimiters.
```python
class Solution:
def returnToBoundaryCount(self, nums: List[int]) -> int:

```

### Answer: (use the provided format with backticks)

This program defines a class `Solution` with a method `returnToBoundaryCount` that takes an array of non-zero integers `nums` as input and returns the number of times the ant returns to the boundary. The program uses a `count` variable to keep track of the number of returns and a `position` variable to track the ant's current position. It iterates over the elements of `nums`, updates the ant's position accordingly, and checks if the ant is on the boundary after each move. If the ant is on the boundary, it increments the `count` variable. Finally, it returns the total count of returns to the boundary.
