 ## 解法
 
-### 方法一
+### 方法一：模拟
+
+我们先计算出矩阵的列数 $cols = \text{len}(encodedText) / rows$，然后按照题目描述的规则，从左上角开始遍历矩阵，将字符添加到答案中。
+
+最后返回答案，注意去掉末尾的空格。
+
+时间复杂度 $O(n)$，空间复杂度 $O(n)$。其中 $n$ 为字符串 $encodedText$ 的长度。

 ## Solutions
 
-### Solution 1
+### Solution 1: Simulation
+
+First, we calculate the number of columns in the matrix $cols = \text{len}(encodedText) / rows$. Then, following the rules described in the problem, we start traversing the matrix from the top left corner, adding characters to the answer.
+
+Finally, we return the answer, making sure to remove any trailing spaces.
+
+The time complexity is $O(n)$, and the space complexity is $O(n)$, where $n$ is the length of the string $encodedText$.
