| "task_description": "Given an array `nums` of `n` integers and an integer `k`, determine whether there exist **two** **adjacent** subarrays of length `k` such that both subarrays are **strictly** **increasing**. Specifically, check if there are **two** subarrays starting at indices `a` and `b` (`a < b`), where: Both subarrays `nums[a..a + k - 1]` and `nums[b..b + k - 1]` are **strictly increasing**. The subarrays must be **adjacent**, meaning `b = a + k`. Return `true` if it is _possible_ to find **two **such subarrays, and `false` otherwise. **Example 1:** **Input:** nums = [2,5,7,8,9,2,3,4,3,1], k = 3 **Output:** true **Explanation:** The subarray starting at index `2` is `[7, 8, 9]`, which is strictly increasing. The subarray starting at index `5` is `[2, 3, 4]`, which is also strictly increasing. These two subarrays are adjacent, so the result is `true`. **Example 2:** **Input:** nums = [1,2,3,4,4,4,4,5,6,7], k = 5 **Output:** false **Constraints:** `2 <= nums.length <= 100` `1 < 2 * k <= nums.length` `-1000 <= nums[i] <= 1000`", |
