Please solve the programming task below using a self-contained code snippet in a markdown code block.

You are given a 0-indexed integer array nums. In one operation you can replace any element of the array with any two elements that sum to it.

For example, consider nums = [5,6,7]. In one operation, we can replace nums[1] with 2 and 4 and convert nums to [5,2,4,7].

Return the minimum number of operations to make an array that is sorted in non-decreasing order.
 
Please complete the following python code precisely:
```python
class Solution:
    def minimumReplacement(self, nums: List[int]) -> int:
```
