concept Sortable = requires(T a) { { std::sort(a.begin(), a.end()) } -> std::same_as<void>; }; // 这个概念要求T类型有begin()和end()方法,并且可以用std::sort函数进行排序 标准库中提供了上百种常用的概念,放在和等头文件中。比较常用的一些有:std::sa...

#include<cstdint>#include<iostream>intmain(){longlonga;int64_tb;std::cin >> a >> b;std::cout << std::max(a, b) << std::endl;return0;} int64_t在64位 Windows 下一般为long long int, 而在64位 Linux 下一般为long int, 所以这段代码在使用64位 Linux 下的 GCC 时不能通过编译,而...

输入多行数时,直到读至输入文件末尾(EOF)为止 说明1:当读到输入结束时,cin >> a >> b返回 0,循环也结束。 说明2:在调试程序时,键盘输入的数据,用CTRL-Z(即按住CTRL键不放,再按下Z)组合作为输入结束,此谓键盘输入设备的“文件末尾”。 重点掌握 Sample Input 1 5 10 20 400 516 Sample Output 6 ...

1.2 sort 中的比较函数 当你需要按照某种特定方式进行排序时,你需要给sort指定比较函数,否则程序会自动提供给你一个比较函数。 vector <int> vect;//...sort(vect.begin(), vect.end());//此时相当于调用sort(vect.begin(), vect.end(), less<int>() ); ...
