You are given a 0-indexed integer array nums and an integer threshold.
Find the length of the longest subarray of nums starting at index l and ending at index r (0 <= l <= r < nums.length) that satisfies the following conditions:
nums[l] % 2 == 0i in the range [l, r - 1], nums[i] % 2 != nums[i + 1] % 2i in the range [l, r], nums[i] <= thresholdReturn an integer denoting the length of the longest such subarray.
\n\nNote: A subarray is a contiguous non-empty sequence of elements within an array.

Example 1:
\n\n\nInput: nums = [3,2,5,4], threshold = 5\nOutput: 3\nExplanation: 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 conditions.\nHence, the answer is the length of the subarray, 3. We can show that 3 is the maximum possible achievable length.\n\n
Example 2:
\n\n\nInput: nums = [1,2], threshold = 2\nOutput: 1\nExplanation: In this example, we can select the subarray that starts at l = 1 and ends at r = 1 => [2]. \nIt satisfies all the conditions and we can show that 1 is the maximum possible achievable length.\n\n\n
Example 3:
\n\n\nInput: nums = [2,3,4,5], threshold = 4\nOutput: 3\nExplanation: In this example, we can select the subarray that starts at l = 0 and ends at r = 2 => [2,3,4]. \nIt satisfies all the conditions.\nHence, the answer is the length of the subarray, 3. We can show that 3 is the maximum possible achievable length.\n\n\n
