截止至今LeetCode题目总量已经有1582题
,估计将来每年平均增长300题
左右,大部分人肯定是刷不完的
,所以得有选择地刷LeetCode。
一种公认的刷题策略是按类别刷题
,可是每个类别也有许多题,在有限的时间里到底该刷哪些题呢
?个人根据LeetCode官方
给出的每个题目的出现频率
,整理并收录了每个类别里高频出现
的题目,对于官方统计频率太低的题目,不予收录,最终得到了这个高频题目表格。
例如,对于下图中题号#275
与#270
的题目将被收录,并且#275
出现频率大于#270��ˮ��,������
;而对于题号#1011
与#1182
的题目,因为出现频率太低,将不被收录:
撸起键盘加油干!祝大家成功上岸!整理不易,点个赞吧!
