A spreadsheet is a grid with 26 columns (labeled from 'A' to 'Z') and a given number of rows. Each cell in the spreadsheet can hold an integer value between 0 and 105.

\n\n

Implement the Spreadsheet class:

\n\n\n\n

Note: If getValue references a cell that has not been explicitly set using setCell, its value is considered 0.

\n\n

Example 1:

\n\n
\n

Input:
\n["Spreadsheet", "getValue", "setCell", "getValue", "setCell", "getValue", "resetCell", "getValue"]
\n[[3], ["=5+7"], ["A1", 10], ["=A1+6"], ["B2", 15], ["=A1+B2"], ["A1"], ["=A1+B2"]]

\n\n

Output:
\n[null, 12, null, 16, null, 25, null, 15]

\n\n

Explanation

\nSpreadsheet spreadsheet = new Spreadsheet(3); // Initializes a spreadsheet with 3 rows and 26 columns
\nspreadsheet.getValue("=5+7"); // returns 12 (5+7)
\nspreadsheet.setCell("A1", 10); // sets A1 to 10
\nspreadsheet.getValue("=A1+6"); // returns 16 (10+6)
\nspreadsheet.setCell("B2", 15); // sets B2 to 15
\nspreadsheet.getValue("=A1+B2"); // returns 25 (10+15)
\nspreadsheet.resetCell("A1"); // resets A1 to 0
\nspreadsheet.getValue("=A1+B2"); // returns 15 (0+15)

Constraints:

\n\n\n", "translatedTitle": "设计电子表格", "translatedContent": "

电子表格是一个网格，它有 26 列（从 'A' 到 'Z'）和指定数量的 rows。每个单元格可以存储一个 0 到 105 之间的整数值。

\n\n

请你实现一个 Spreadsheet 类：

\n\n\n\n

注意： 如果 getValue 引用一个未通过 setCell 明确设置的单元格，则该单元格的值默认为 0 。

\n\n

 

\n\n

示例 1：

\n\n
\n

输入：
\n[\"Spreadsheet\", \"getValue\", \"setCell\", \"getValue\", \"setCell\", \"getValue\", \"resetCell\", \"getValue\"]
\n[[3], [\"=5+7\"], [\"A1\", 10], [\"=A1+6\"], [\"B2\", 15], [\"=A1+B2\"], [\"A1\"], [\"=A1+B2\"]]

\n\n

输出：
\n[null, 12, null, 16, null, 25, null, 15]

\n\n

解释

\nSpreadsheet spreadsheet = new Spreadsheet(3); // 初始化一个具有 3 行和 26 列的电子表格
\nspreadsheet.getValue(\"=5+7\"); // 返回 12 (5+7)
\nspreadsheet.setCell(\"A1\", 10); // 设置 A1 为 10
\nspreadsheet.getValue(\"=A1+6\"); // 返回 16 (10+6)
\nspreadsheet.setCell(\"B2\", 15); // 设置 B2 为 15
\nspreadsheet.getValue(\"=A1+B2\"); // 返回 25 (10+15)
\nspreadsheet.resetCell(\"A1\"); // 重置 A1 为 0
\nspreadsheet.getValue(\"=A1+B2\"); // 返回 15 (0+15)
