  "task_description": "A cell `(r, c)` of an excel sheet is represented as a string `\"<col><row>\"` where: `<col>` denotes the column number `c` of the cell. It is represented by **alphabetical letters**. For example, the `1st` column is denoted by `'A'`, the `2nd` by `'B'`, the `3rd` by `'C'`, and so on. `<row>` is the row number `r` of the cell. The `rth` row is represented by the **integer** `r`. You are given a string `s` in the format `\"<col1><row1>:<col2><row2>\"`, where `<col1>` represents the column `c1`, `<row1>` represents the row `r1`, `<col2>` represents the column `c2`, and `<row2>` represents the row `r2`, such that `r1 <= r2` and `c1 <= c2`. Return _the **list of cells**_ `(x, y)` _such that_ `r1 <= x <= r2` _and_ `c1 <= y <= c2`. The cells should be represented as **strings** in the format mentioned above and be sorted in **non-decreasing** order first by columns and then by rows. **Example 1:** ``` **Input:** s = \"K1:L2\" **Output:** [\"K1\",\"K2\",\"L1\",\"L2\"] **Explanation:** The above diagram shows the cells which should be present in the list. The red arrows denote the order in which the cells should be presented. ``` **Example 2:** ``` **Input:** s = \"A1:F1\" **Output:** [\"A1\",\"B1\",\"C1\",\"D1\",\"E1\",\"F1\"] **Explanation:** The above diagram shows the cells which should be present in the list. The red arrow denotes the order in which the cells should be presented. ``` **Constraints:** `s.length == 5` `'A' <= s[0] <= s[3] <= 'Z'` `'1' <= s[1] <= s[4] <= '9'` `s` consists of uppercase English letters, digits and `':'`.",
