-### 方法一
+### 方法一：模拟
+
+我们可以逐行和逐列遍历矩阵，找到连续三个相同的元素，将它们标记为负数。如果成功标记，我们需要将矩阵中的元素下移，直到没有元素可以下移为止。
+
+时间复杂度 $O(m^2 \times n^2)$，其中 $m$ 和 $n$ 分别是矩阵的行数和列数。空间复杂度 $O(1)$。

-### Solution 1
+### Solution 1: Simulation
+
+We can traverse the matrix row by row and column by column to find three consecutive identical elements and mark them as negative numbers. If marking is successful, we need to move the elements in the matrix down until no elements can move down.
+
+The time complexity is $O(m^2 \times n^2)$, where $m$ and $n$ are the number of rows and columns of the matrix, respectively. The space complexity is $O(1)$.

+### Solution 3: Two Pointers (Optimization)
+
+In Solution 2, we move the left pointer in a loop until $cnt \leq 1$. Since the problem asks for the longest subarray, it means we don't need to reduce the length of the subarray. Therefore, if $\textit{cnt} \gt 1$, we only move the left pointer once, and the right pointer continues to move to the right. This ensures that the length of the subarray does not decrease.
+
+Finally, the answer we return is $n - l - 1$, where $l$ is the position of the left pointer.
+
+The time complexity is $O(n)$, where $n$ is the length of the array $nums$. The space complexity is $O(1)$.

+### Solution 2: Two Pointers (Optimization)
+
+Since the problem only requires us to find the length of the longest semi-repetitive substring, each time the number of adjacent identical characters in the interval exceeds $1$, we can move the left pointer $l$ once, while the right pointer $r$ continues to move to the right. This ensures that the length of the substring does not decrease.
+
+Finally, the answer is $n - l$, where $n$ is the length of the string.
+
+The time complexity is $O(n)$, where $n$ is the length of the string. The space complexity is $O(1)$.
