Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

The test cases do not adequately cover all cases it seems, this incorrect solution was able to pass all of the current ones:

class Solution:
def maxSlidingWindow(self, nums: List[int], k: int) -> List[int]:
l, r = 0, 0
max_num, sec_max = -10000, -10000

    while ((r-l) < (k-1)):
        if (nums[r] > max_num):
            max_num = nums[r]
            sec_max = -10000
        elif (nums[r] > sec_max):
            sec_max = nums[r]
        r += 1
    
    res = []

    while (r < len(nums)):
        if (nums[r] > max_num):
            max_num = nums[r]
            sec_max = -10000
        elif (nums[r] > sec_max):
            sec_max = nums[r]

        res.append(max_num)

        if (nums[l] == max_num):
            max_num = sec_max
            sec_max = -10000
        l += 1
        r += 1
    
    return res

A test case with a descending array should address this, such as:
[5, 4, 3, 2, 1] k= 3
