像这样的对象内数组 如何进行去重 合并：合并后

[{
                "problems": "环境认识障碍综合征",
                "implement": [
                    {
                        "name": "记忆训练",
                        "id": "593644b12455b42ab4aa735d"
                    },
                    {
                        "name": "神经系统检测",
                        "id": "5953488d0737cd9105d5f2ae"
                    },{
                        "name": "促进脑灌注",
                        "id": "5953483e0737cd9105d5f2ac"
                    }
                ]
            },{
                "problems": "记忆受损",
                "implement": [
                    {
                        "name": "记忆训练",
                        "id": "593644b12455b42ab4aa735d"
                    },
