c_cpp C ++查找MinMax和向量索引

Posted 2021-05-14

#include <algorithm>
#include <vector>

vector<double> v;

vector<double>::iterator it = min_element(v.begin(), v.end());
int minIndex = it - v.begin();
double minValue = *it;

// The above is slower (about twice as slow) than the following though:
for(int i=0; i<v.size(); i++) {
  if(minValue>v[i]) {
    minValue = v[i];
    minIndex = i;
  }
}
