It\u0027s not allowed to submit in a replay directly, instead one should practice in a clone of a replay.\n\nA [replay] contains only problem set information and rank of the original contest. You can see replay\u0027s rank synchronously during practicing, as long as you are practicing in a clone of a replay.\n\n\n#### Create a replay\nSince original rank data varies amongst different sources, Virtual Judge is not clever enough to realize them automatically. You are supposed to prepare an Excel file using original rank data before importing it into Virtual Judge. Here is an example of creating a replay:\n\n\u003ciframe id\u003d\"trc\" width\u003d\"1024\" height\u003d\"640\" src\u003d\"//player.bilibili.com/player.html?bvid\u003dBV1C44y137P2\u0026page\u003d1\" scrolling\u003d\"no\" border\u003d\"0\" frameborder\u003d\"no\" framespacing\u003d\"0\" allowfullscreen\u003d\"true\"\u003e \u003c/iframe\u003e\n\n\u003ciframe id\u003d\"nkq\" width\u003d\"560\" height\u003d\"315\" src\u003d\"https://www.youtube.com/embed/CEBRY1_qfoI\" frameborder\u003d\"0\" allowfullscreen\u003e\u003c/iframe\u003e\n\n\u003cscript\u003e\nsetTimeout(function(event) { \n const elem \u003d document.querySelector(navigator.language \u003d\u003d\u003d \u0027zh-CN\u0027 ? \u0027#nkq\u0027 : \u0027#trc\u0027);\n elem.parentNode.removeChild(elem);\n}, 200);\n\u003c/script\u003e\n\n\u003cbr\u003e\n\n#### Note\n* Unlike Codeforces::Gym, Virtual Judge replays are created using RANK instead of SUBMISSIONS. Therefore they lose the the timestamp information of each failed submission, whilst they preserve correct rank order (top team, 2nd, 3rd and so on) of each moment.\n* Although not demanded, please provide the correct begin time of the actual original contest, and reference page URL in description field.\n* Please don\u0027t create **messy replays** and **duplicate replays**, because they will disturb others\u0027 contests. I will delete these replays without informing you.","threadId":12443,"likeCnt":15,"createTime":1490525463000,"isWorkbook":false,"viewCnt":11264,"openness":2,"fav":false,"id":87,"trustable":true}
