有关从老 OJ 迁移后题面与数据的兼容性问题

Legacy OnlineJudge 所有题库与测试数据已完成迁移与评测测试，已可在本 OJ 评测老 OJ 题目。

老 OJ 题号加 10000 即为新 OJ 题号，如，老 OJ 1000 -> 新 OJ 11000。

由于没有标程而无法得知数据正确性的题目如下： 11077, 11099, 11102, 11103, 11104, 11105, 11106, 11126, 11140, 11199, 11203, 11206, 11211, 11221, 11225, 11226, 11228, 11231, 11236, 11246, 11251, 11267, 11271, 11278, 11284, 11305, 11311, 11314, 11319, 11325, 11348, 11349, 11358, 11359, 11367, 11369, 11370, 11371, 11393, 11406, 11407, 11413, 11510, 11545, 11547, 11548, 11559, 11564, 11566, 11572, 11588, 11630, 11636, 12202, 13008, 13013, 13024, 13034, 13037, 13039, 13042, 14001, 14002, 14003, 14004, 14005, 14006, 14007, 14012, 14013, 14025, 14053, 14057, 14058, 14093, 14096, 14141, 14155, 14179, 14200, 14201, 14212, 14231, 14232, 14276, 14277, 14286, 14293, 14296, 14297, 14302, 14303, 14323, 14337
