在Lua表中查找重复的值

function findDuplicates(table)
    local values = {}
    local duplicates = {}

    for _, value in pairs(table) do
        if values[value] then
            duplicates[value] = true
        else
            values[value] = true
        end
    end

    local result = {}
    for value, _ in pairs(duplicates) do
        table.insert(result, value)
    end

    return result
end

-- 示例用法
local myTable = {1, 2, 3, 4, 2, 5, 3, 6}
local duplicates = findDuplicates(myTable)

print("重复的值：")
for _, value in ipairs(duplicates) do
    print(value)
end

重复的值：
