TreeMap：它会依据键的自然顺序，或者根据创建时提供的比较器（Comparator）来对键值对进行排序。下面为你展示这两种有序映射的用法，以及如何获取它们的大小：java import java.util.LinkedHashMap;import java.util.TreeMap;public class OrderedMapExample { public static void main(String[] args) { // Linked...

7. Custom Sorting in std::set You can customize the sorting order by providing a comparator when declaring the set.#include <set> #include <iostream> #include <string> struct DescendingOrder { bool operator()(const std::string &a, const std::string &b) const { return a > b; // ...
