PS:位运算代码如下 classSolution{public:intfindMaximumXOR(vector<int>&nums){intres=0;intmask=0;for(inti=31;i>=0;i--){mask=mask|1<<i;unordered_set<int>s;for(autonum:nums)s.insert(num&mask);intexcept=res|1<<i;for(autonum:s)if(s.find(except^num)!=s.end()){res=except;break;}}...
首先复习一下异或运算规则:两个二进制的数字,同一个位置上的数字不同,XOR 为 1;数字相同的时候,XOR 为 0。所以这里如果要找 XOR 最大的结果,最好能找到两个数字,他们的二进制表达最好在每一位上都不同。而且 XOR 是具有交换律的,如果你有 a ^ b = c,你同时可以得到 a ^ c = b 和 b ^ c = ...
