如何按指定条件生成Jolt输出：新增用户及社区条目

输入数据包含v3_users数组（初始含3条用户详细信息）和v2_communities数组（初始含2个社区条目），需实现以下逻辑：

• 新增用户时，将该用户的所有字段信息添加至v3_users子数组；
• 每新增一名用户，需在v2_communities数组中添加一个新的community条目（如本次添加community3，下次依次递增编号）。

输入示例 #

{
    "v3_users": [
        {
            "username": "user1",
            "password": "password1",
            "privacy_password": "privacy1"
        },
        {
            "username": "user2",
            "password": "password2",
            "privacy_password": "privacy2",
            "engineId":"80000000308"
        },
        {
            "username": "user3",
            "password": "password3",
            "privacy_password": "privacy3",
            "engineId":"8000020305"
        }
    ],
    "v2_communities": ["community1","community2"]
}

输出示例 #

{
    "v3_users": [
        {
            "username": "user1",
            "password": "password1",
            "privacy_password": "privacy1"
        },
        {
            "username": "user2",
            "password": "password2",
            "privacy_password": "privacy2",
            "engineId":"80000000308"
        },
        {
            "username": "user3",
            "password": "password3",
            "privacy_password": "privacy3",
            "engineId":"8000020305"
        },
        {
            "username": "user4",
            "password": "password4",
            "privacy_password": "privacy4",
            "engineId":"80000203078"
        }
    ],
    "v2_communities": ["community1","community2","community3"]
}
