Invalid parameter index 1.

这个错误通常是由于 SQL 查询语句中的占位符数量不正确导致的。请检查您的 SQL 查询语句中的占位符数量是否与您提供的参数数量相匹配。例如，如果您的查询语句中有一个占位符（使用问号表示），则您必须传递一个参数，如果有两个占位符，则必须传递两个参数，以此类推。请确保您的查询语句和参数数量匹配，如果您仍然遇到问题，请提供更多信息，以便我能够更好地帮助您解决问题。

很抱歉，由于我是一个自然语言生成模型，我无法直接解决你的代码问题，因为我不能运行代码。但是我可以给你一些建议来解决你的问题。

首先，根据报错信息，你的函数调用 `wx.cloud.callFunction` 中的参数有误。你需要检查你的代码，确保你传给云函数的参数是正确的。

其次，你的代码中使用了 `.counter('fetch')`，但是你没有提供这个函数。你需要确你的代码中所有使用的函数都已经定义。

最后，你的代码中使用了 `setData` 来更新页面状态，确保你已经在页面中定义了对应的变量。同时，你需要确保你的代码中没有重复定义或更新同一个变量，这可能会导致意外的行为和错误。

希望这些建议能够帮助你解决问题。如果你需要更多帮助，建议你向相关技术社区寻求帮助。

We consider in this exercise the validation of a Sudoku grid. The Sudoku a mathematical game. You do not need to know this game to make this exercise. A solved Sudoku grid is represented on the right. It is a grid composed of 9 lines and 9 columns. A grid is said to be valid if it respects the following rules : • each line contains exactly once each value from 1 to 9 • each column contains exactly once each value from 1 to 9 • each block contains exactly once each value from 1 to 9. A block is a square of 3 × 3 cells. There are 9 blocks in the grid, they are delimited in the example grid with the bold lines. Q1) Create a class Sudoku containing a main() method. Declare a variable named grid corresponding to a sudoku grid. Your grid may correspond to the example which is valid, or not (for example an invalid grid filled with 1's). Q2) Write a static function named validLine() that has two parameters : a grid and a line index i. This function checks if the line i is valid (i.e. contains exactly once each value from 1 to 9) or not. It may be useful to write and use another function that counts the number of occurrences of a given value k in the line i. Q3) Write a static method allLinesValid() that takes a grid as parameter and checks if all the lines are valid. You may use the previous method, even if you did not write it.

Sure, I can help with that! Here's the implementation of the Sudoku class with the main() method, validLine() static method, and allLinesValid() static method:

class Sudoku:
    def main(self):
        # Declare a variable named grid corresponding to a sudoku grid
        grid = [
            [5, 3, 4, 6, 7, 8, 9, 1, 2],
            [6, 7, 2, 1, 9, 5, 3, 4, 8],
            [1, 9, 8, 3, 4, 2, 5, 6, 7],
            [8, 5, 9, 7, 6, 1, 4, 2, 3],
            [4, 2, 6, 8, 5, 3, 7, 9, 1],
            [7, 1, 3, 9, 2, 4, 8, 5, 6],
            [9, 6, 1, 5, 3, 7, 2, 8, 4],
            [2, 8, 7, 4, 1, 9, 6, 3, 5],
            [3, 4, 5, 2, 8, 6, 1, 7, 9]
        ]

        # Check if the grid is valid
        print(self.isValid(grid))

    @staticmethod
    def validLine(grid, i):
        # Check if the line i is valid (i.e. contains exactly once each value from 1 to 9)
        for j in range(1, 10):
            if grid[i].count(j) != 1:
                return False
        return True

    @staticmethod
    def allLinesValid(grid):
        # Check if all the lines are valid
        for i in range(0, 9):
            if not Sudoku.validLine(grid, i):
                return False
        return True

    def isValid(self, grid):
        # Check if the grid is valid (i.e. each line, column, and block contains exactly once each value from 1 to 9)
        for i in range(0, 9):
            # Check if the line i is valid
            if not Sudoku.validLine(grid, i):
                return False

            # Check if the column i is valid
            column = [grid[j][i] for j in range(0, 9)]
            if not Sudoku.validLine(column, 0):
                return False

            # Check if the block i is valid
            block = []
            for j in range(0, 3):
                for k in range(0, 3):
                    block.append(grid[(i // 3) * 3 + j][(i % 3) * 3 + k])
            if not Sudoku.validLine(block, 0):
                return False

        return True

To test the implementation, you can create an instance of the Sudoku class and call the main() method:

sudoku = Sudoku()
sudoku.main()

This will output True if the grid is valid, and False otherwise.
