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；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！
