 ## Description
+Given an array `nums` of `n` integers, your task is to find the **maximum** value of `k` for which there exist **two** adjacent subarrays of length `k` each, such that both subarrays are **strictly increasing**. Specifically, check if there are **two** subarrays of length `k` 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 the **maximum** possible value of `k`.
+
+A **subarray** is a contiguous **non-empty** sequence of elements within an array.
 
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
-```
+Input: nums = [2,5,7,8,9,2,3,4,3,1]

-Adjacent Increasing Subarrays Detection II
-```go
+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, and 3 is the maximum possible value of k for which two such adjacent strictly increasing subarrays exist.
 ```
 
+**Example 2:**
+
+```
+Input: nums = [1,2,3,4,4,4,4,5,6,7]
+
+Output: 2
+
+Explanation:
+
+The subarray starting at index 0 is [1, 2], which is strictly increasing.
+The subarray starting at index 2 is [3, 4], which is also strictly increasing.
+These two subarrays are adjacent, and 2 is the maximum possible value of k for which two such adjacent strictly increasing subarrays exist.
+```
