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！
