代码简洁很多,实测下降到9ms,beats 46.70% of cpp submissions。 看来set.count()这个函数效果还可以。 4、改进2: 我们能不能只定义一个set,然后依旧单重循环+set.count()。代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 vector<int> intersection(vector<int>& nums1, vector<int>& nums2...

In the charts above, you’ll see the first column represents our baseline where no JavaScript was run at all. The next two columns represent the first type of test. The Mac ran both quite well as I would expect for a top-end machine for development. The Windows machine gave us a diffe...
