    2194 - Cells in a Range on an Excel Sheet.

    Easy

    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 ':'.
