Find the length of the longest subarray of numsstarting at index land ending at index r(0 <= l <= r < )that satisfies the following conditions:

nums[l] % 2 == 0

For all indices iin the range [l, r - 1], nums[i] % 2 != nums[i + 1] % 2

For all indices iin the range [l, r], nums[i] <= threshold

Return an integer denoting the length of the longest such subarray.

Note: A subarray is a contiguous non-empty sequence of elements within an array.

Example 1:

Input: nums = [3,2,5,4], threshold = 5

Output: 3

Explanation: In this example, we can select the subarray that starts at l = 1 and ends at r = 3 => [2,5,4]. This subarray satisfies the , the answer is the length of the subarray, 3. We can show that 3 is the maximum possible achievable length.

Example 2:

Input: nums = [1,2], threshold = 2

Output: 1

Explanation: In this example, we can select the subarray that starts at l = 1 and ends at r = 1 => [2]. It satisfies all the conditions and we can show that 1 is the maximum possible achievable length.

Example 3:

Input: nums = [2,3,4,5], threshold = 4

Output: 3

Explanation: In this example, we can select the subarray that starts at l = 0 and ends at r = 2 => [2,3,4]. It satisfies all the , the answer is the length of the subarray, 3. We can show that 3 is the maximum possible achievable length.

Constraints:

1 <= <= 100

1 <= nums[i] <= 100

1 <= threshold <= 100

周赛的题目；卡了一下，没有考虑长度为1 的情况；
