This post will discuss how to find the min or max value in a vector in C++. 1. Usingstd::max_element Thestd::min_elementandstd::max_elementreturn an iterator to the minimum and the maximum value in the specified range, respectively. The following code example shows invocation for both ...
其中第二个参数位置的元素将处于正确位置，其他位置元素的顺序可能是任意的，但前面的都比它小，后面的都比它大●nth_element()是c++的STL库中的函数，作用是将数组中第k小的整数放在区间第k个位置●比如vector<int> nums = {9, 7, 5, 11, 12, 2, 14, 3, 10, 6};●nth_element会重新排列序列，使得...
// min_element/max_element example #include <iostream> // std::cout #include <algorithm> // std::min_element, std::max_element bool myfn(int i, int j) { return i<j; } struct myclass { bool operator() (int i,int j) { return i<j; } } myobj; int main () { int myint...
std :: minmax_element的复杂度为max(floor(3/2(N-1)),0)其中std :: max_element和std :: min_element都是max(N-1,0)所以大约是25使用std :: minmax_element减少运算次数 There is also a difference wherestd::minmax_elementfinds the last largest element whilestd::max_elementfinds the first larg...
vector<int>data={1,3,2,5,4};autoit=max_element(begin(data),end(data));// it is now equal to begin(data)+3// where *it is 5 and *it-begin(data) is 3, ie. the index. C++ 11 minmax_element Sometimes, we want to know the min and max – and instead of doing two passes,...
当vector(或任何容器)为空时,即开始迭代器和结束迭代器相等,std::min_element将返回一个迭代器,该迭代器等于传入的结束迭代器。这意味着返回的迭代器不指向容器中的任何有效元素。 3. 给出结论:当vector数组为空时,std::min_element会得到什么值 当vector数组为空时,std::min_element会返回一个迭代器,该迭代...
C++ STL program to demonstrate use of std::min_element() functionIn this program, we have an array and a vector and finding their smallest elements. //C++ STL program to demonstrate use of //std::min_element() function #include <iostream> #include <algorithm> #include <vector> using ...
max和min还可以比较集合的大小。比如:set,multiset,vector,list,queue,stack,map,multimap.因为集合重载了比较操作符。此外,string,非STL标准的hash_set,hash_map都可以。 minmax Compares two input parameters and returns them as a pair, in order of least to greatest. ...
Min 功能说明按element求最小值,公式表达如下,其中PAR表示矢量计算单元一个迭代能够处理的元素个数: 函数原型tensor前n个数据计算:template <typename ……欲了解更多信息欢迎访问华为HarmonyOS开发者官网
