以下是一个二维数组，将被1包围的0改为1，写成lua代码 local arr = { {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 1, 1, 1, 0, 0, 0, 0}, {0, 0, 1, 0, 0, 0, 1, 0, 0, 0}, {0, 0, 0, 1, 1, 1, 0, 0, 0, 0}, {0, 0, 1, 0, 0, 0, 1, 0, 0, 0}, {0, 0, 0, 1, 1, 1, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}, }

以下是将被1包围的0改为1的lua代码：

-- 定义一个函数，用于将被1包围的0改为1
function change(arr)
    -- 数组的行数和列数
    local m, n = #arr, #arr[1]

    -- 定义一个标记数组，用于标记哪些元素需要被改为1
    local flag = {}

    -- 遍历第一行和最后一行，将值为0的元素及其周围的元素标记
    for i = 1, n do
        if arr[1][i] == 0 then
            flag[1 .. "," .. i] = true
            if i > 1 then
                flag[1 .. "," .. (i - 1)] = true
            end
            if i < n then
                flag[1 .. "," .. (i + 1)] = true
            end
        end
        if arr[m][i] == 0 then
            flag[m .. "," .. i] = true
            if i > 1 then
                flag[m .. "," .. (i - 1)] = true
            end
            if i < n then
                flag[m .. "," .. (i + 1)] = true
            end
        end
    end

    -- 遍历第一列和最后一列，将值为0的元素及其周围的元素标记
    for i = 2, m - 1 do
        if arr[i][1] == 0 then
            flag[i .. "," .. 1] = true
            if i > 1 then
                flag[(i - 1) .. "," .. 1] = true
            end
            if i < m then
                flag[(i + 1) .. "," .. 1] = true
            end
        end
        if arr[i][n] == 0 then
            flag[i .. "," .. n] = true
            if i > 1 then
                flag[(i - 1) .. "," .. n] = true
            end
            if i < m then
                flag[(i + 1) .. "," .. n] = true
            end
        end
    end

    -- 遍历数组，将标记为true的元素改为1
    for i = 1, m do
        for j = 1, n do
            if flag[i .. "," .. j] then
                arr[i][j] = 1
            end
        end
    end

    -- 返回修改后的数组
    return arr
end

-- 调用函数，将被1包围的0改为1
local arr = {
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
    {0, 0, 1, 0, 0, 0, 1, 0, 0, 0},
    {0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
    {0, 0, 1, 0, 0, 0, 1, 0, 0, 0},
    {0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
    {0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
}
arr = change(arr)
