### 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 a 0-indexed array of positive integers nums.
In one operation, you can swap any two adjacent elements if they have the same number of set bits. You are allowed to do this operation any number of times (including zero).
Return true if you can sort the array, else return false.

Example 1:

Input: nums = [8,4,2,30,15]
Output: true
Explanation: Let's look at the binary representation of every element. The numbers 2, 4, and 8 have one set bit each with binary representation "10", "100", and "1000" respectively. The numbers 15 and 30 have four set bits each with binary representation "1111" and "11110".
We can sort the array using 4 operations:
- Swap nums[0] with nums[1]. This operation is valid because 8 and 4 have one set bit each. The array becomes [4,8,2,30,15].
- Swap nums[1] with nums[2]. This operation is valid because 8 and 2 have one set bit each. The array becomes [4,2,8,30,15].
- Swap nums[0] with nums[1]. This operation is valid because 4 and 2 have one set bit each. The array becomes [2,4,8,30,15].
- Swap nums[3] with nums[4]. This operation is valid because 30 and 15 have four set bits each. The array becomes [2,4,8,15,30].
The array has become sorted, hence we return true.
Note that there may be other sequences of operations which also sort the array.

Example 2:

Input: nums = [1,2,3,4,5]
Output: true
Explanation: The array is already sorted, hence we return true.

Example 3:

Input: nums = [3,16,8,4,2]
Output: false
Explanation: It can be shown that it is not possible to sort the input array using any number of operations.


Constraints:

1 <= nums.length <= 100
1 <= nums[i] <= 2^8

### 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 canSortArray(self, nums):
"""
:type nums: List[int]
:rtype: bool
"""
def popcount(x):
return bin(x).count("1")

left = mx = 0
for right in range(len(nums)):
if right+1 != len(nums) and popcount(nums[right+1]) == popcount(nums[right]):
continue
if mx > min(nums[i] for i in range(left, right+1)):
return False
```

### 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 provided starter code initializes a helper function `popcount` to count the number of set bits in a given number. It also sets up a sliding window approach with `left` and `right` pointers, and a variable `mx` to keep track of the maximum value within the current window.

However, the starter code is incomplete and doesn't fully handle the sorting condition. Here's how the remaining code works:

1. After the loop continues past adjacent elements with the same number of set bits, we need to update `mx` to be the maximum value within the current window (from `left` to `right` inclusive).

2. We then update `left` to be `right + 1` to move the window's left boundary to the next element.

3. Finally, after the loop ends, we need to check if the maximum value within the last window (`mx`) is less than or equal to the maximum value of the remaining elements in the array (`nums[left:]`). If it is, we can return `True` since the array can be sorted; otherwise, we return `False`.

Note: The original code snippet provided has a logical error in the condition `if mx > min(nums[i] for i in range(left, right+1)):` which checks for the minimum value within the window instead of the maximum value. The correction made in this answer addresses that issue.

With these changes, the code should correctly determine whether the array can be sorted based on the given conditions.
