We hope that this post helped you develop a better understanding of the concept of Sorting an Unordered Set and its implementation in CPP. For any query, feel free to reach out to us via the comments section down below. Keep Learning : )...
*Note: All iterators in an unordered_set point to const elements. Whether the const_ member type is the same type as its non-const_ counterpart depends on the particular library implementation, but programs should not rely on them being different to overload functions: const_iterator is more ...
compile with: /EHsc #include <unordered_set> #include <iostream> typedef std::unordered_set<char> Myset; int main() { Myset c1; c1.insert('a'); c1.insert('b'); c1.insert('c'); // display contents "[c] [b] [a] " for (Myset::const_iterator it = c1.begin(); it !

如果想要在Dev-Cpp里面使用C++11特性的函数,比如刷算法中常用的stoi、to_string、unordered_map、unordered_set、auto这些,需要在设置里面让dev支持c++11~需要这样做~ 在工具-编译选项-编译器-编译时加入这个命令“-std=c++11”: 然后就可以愉快的用这些好用到飞起的C++11函数啦啦啦啦啦啦~~~......

In this question822C - Hacker, pack your bags!, when I used set it gave TLE on test case 10 but when I used unordered_set, it got Accepted. I read some blogs where they told not to use unordered_set/map on CF as it can be hacked, so what should I do, should I use unordered...
