So if we sort the first row in descending order the output will be: [[3, 5, 4], [6, 4, 2], [7, 3, 1]] Example #include <bits/stdc++.h>usingnamespacestd;voidprint(vector<vector<int>>two_D_vector) {for(autoit:two_D_vector) {//it is now an 1D vectorfor(autoij:it) {...
end(), customCompare); // 输出排序后的结果 std::cout << "Sorted vector in descending order: "; for (int num : vec) { std::cout << num << " "; } std::cout << std::endl; return 0; } 代码说明 包含必要的头文件: #include <iostream> ...
myvector contains: 12 26 32 33 45 53 71 80 3个参数的情况 sort(first,last,comp); 第三个参数comp主要用来指明排序顺序,即升序还是降序。 比如在数组中: // C++ program to demonstrate descending order sort using // greater<>(). #include <bits/stdc++.h> using namespace std; int main() {...
We will pass this function into the // third parameter and it will tell it to sort descendingly. bool wayToSort(int i, int j) { return i > j; } int main() { vector<int> intVec = {56, 32, -43, 23, 12, 93, 132, -154}; // Do not include the () when you call wayTo...

输出: Writing to the smaller vector in ascending order gives: 1 2 3 The return value is the end iterator Writing to the larger vector in descending order gives: 5 4 3 2 1 15 16 The return value is the iterator to 15参阅partial_sort 排序一个范围的前 N 个元素 (函数模板) sort...
