### Instructions: You are an expert Python programmer. You will be given a question (problem specification) and the first lines of Python solution to this problem, and will write in Python the remaining lines of the program to produce a correct Python program that matches the specification and passes all tests. You will NOT return anything except for the second part of the program that you wrote.
### Question:
You are given two 0-indexed integer arrays, nums1 and nums2, both having length n.
You are allowed to perform a series of operations (possibly none).
In an operation, you select an index i in the range [0, n - 1] and swap the values of nums1[i] and nums2[i].
Your task is to find the minimum number of operations required to satisfy the following conditions:

nums1[n - 1] is equal to the maximum value among all elements of nums1, i.e., nums1[n - 1] = max(nums1[0], nums1[1], ..., nums1[n - 1]).
nums2[n - 1] is equal to the maximum value among all elements of nums2, i.e., nums2[n - 1] = max(nums2[0], nums2[1], ..., nums2[n - 1]).

Return an integer denoting the minimum number of operations needed to meet both conditions, or -1 if it is impossible to satisfy both conditions.

Example 1:

Input: nums1 = [1,2,7], nums2 = [4,5,3]
Output: 1
Explanation: In this example, an operation can be performed using index i = 2.
When nums1[2] and nums2[2] are swapped, nums1 becomes [1,2,3] and nums2 becomes [4,5,7].
Both conditions are now satisfied.
It can be shown that the minimum number of operations needed to be performed is 1.
So, the answer is 1.

Example 2:

Input: nums1 = [2,3,4,5,9], nums2 = [8,8,4,4,4]
Output: 2
Explanation: In this example, the following operations can be performed:
First operation using index i = 4.
When nums1[4] and nums2[4] are swapped, nums1 becomes [2,3,4,5,4], and nums2 becomes [8,8,4,4,9].
Another operation using index i = 3.
When nums1[3] and nums2[3] are swapped, nums1 becomes [2,3,4,4,4], and nums2 becomes [8,8,4,5,9].
Both conditions are now satisfied.
It can be shown that the minimum number of operations needed to be performed is 2.
So, the answer is 2.

Example 3:

Input: nums1 = [1,5,4], nums2 = [2,5,3]
Output: -1
Explanation: In this example, it is not possible to satisfy both conditions.
So, the answer is -1.


Constraints:

1 <= n == nums1.length == nums2.length <= 1000
1 <= nums1[i] <= 10^9
1 <= nums2[i] <= 10^9

### Format: You will use the following starter code to write the solution to the problem and enclose your code within delimiters.
```python
class Solution(object):
def minOperations(self, nums1, nums2):
"""
:type nums1: List[int]
:type nums2: List[int]
:rtype: int
"""
cnt = [0]*2
for x, y in zip(nums1, nums2):
if not (min(x, y) <= min(nums1[-1], nums2[-1]) and max(x, y) <= max(nums1[-1], nums2[-1])):
return -1
if not (x <= nums1[-1] and y <= nums2[-1]):
cnt[0] += 1
```

### Answer: (enclose your partial completion in backticks. Only write the missing portion of the code, not the entire code. Be very careful to match the appropriate indentation. Directly appending your code after the partial code should produce a correct completion solution.)

### Explanation:

The given partial solution checks if there are any elements in `nums1` and `nums2` that violate the conditions of being less than or equal to the maximum values of both arrays. If such elements exist, it immediately returns -1.

To complete the solution, we need to handle the cases where the last elements of `nums1` and `nums2` are not already the maximum values of their respective arrays. We also need to keep track of the number of operations performed.

Here's the logic to handle the remaining cases:

1. Find the maximum values of `nums1` and `nums2` using the `max` function and store them in `max_val1` and `max_val2`, respectively.
2. Check if both the last elements of `nums1` and `nums2` are not the maximum values of their respective arrays. If this is the case, we need to perform at least one operation.


* Increment `cnt[0]` by 1 to account for this operation.
* Check if either of the last elements is greater than the maximum value of the other array. If so, it is impossible to satisfy the conditions, and we return -1.
* Otherwise, increment `cnt[1]` by 1 to indicate that we might need to perform another operation to swap the maximum value into its correct position.
3. If only the last element of `nums1` is not the maximum value, check if `max_val1` exists in `nums2`. If it does, we can swap it into the correct position in `nums1`, so increment `cnt[1]` by 1. If it doesn't exist, it is impossible to satisfy the conditions, and we return -1.
4. Similarly, if only the last element of `nums2` is not the maximum value, check if `max_val2` exists in `nums1`. If it does, increment `cnt[1]` by 1. If it doesn't exist, return -1.
5. Finally, return the minimum number of operations needed. If `cnt[0]` is greater than 0, it means we performed at least one operation. In this case, we return the minimum between `cnt[0]` and `cnt[0] + cnt[1]`. The reason for this is that if `cnt[1]` is 0, we don't need any additional operations, but if `cnt[1]` is greater than 0, it means we might need to perform another operation to swap the maximum value into its correct position. However, if `cnt[0]` is 0, it means we didn't perform any operations, so we simply return 0.

Note: The code assumes that the input arrays `nums1` and `nums2` are valid and satisfy the given constraints.		 class Solution(object): def minOperations(self, nums1, nums2): """ :type nums1: List[int] :type nums2: List[int] :rtype: int """ cnt = [0]*2 for x, y in zip(nums1, nums2): if not (min(x, y) <= min(nums1[-1], nums2[-1]) and max(x, y) <= max(nums1[-1], nums2[-1])): return -1 if not (x <= nums1[-1] and y <= nums2[-1]): cnt[0] += 1 if not (x <= nums2[-1] and y <= nums1[-1]): cnt[1] += 1 return min(cnt)
