@[hunxuewangzi](/user/299377) 你要log的做法就没法做

草是set

那该怎么写啊
by hunxuewangzi @ 2020-03-26 19:21:07
放弃set，使用vector（雾
by andyli @ 2020-03-26 19:21:49
@[hunxuewangzi](/user/299377) 别想着用set了，真要做去写平衡树
by Marser @ 2020-03-26 19:22:01
@[hunxuewangzi](/user/299377) 不过你可以手写平衡树，或者在允许的时候使用pbds rb_tree，当然对效率要求不高或者只有查询的时候可以使用vector
