min_element() in C++

min_element(): This is a build-in function in STL. This function is available in the file stl_algo.h. This function returns an iterator pointing to the element with the smallest value in the range [first, last).

Syntax:

std::min_element(__first,__last)

Parameters: Two parameters are required for this function.

__first – Start of range.

 __last – End of range.

For Example:

arr = {5,34,3,12,4,21}

vector<int>::iterator it = min_element(arr.beigin(),arr.end()) = > It returns an iterator pointing to 3.

Approach

C++

#include <bits/stdc++.h>
using namespace std;

int main()
{
    vector<int> arr = {5, 34, 3, 12, 4, 21};

    vector<int>::iterator it = min_element(arr.begin(), 
                               arr.end());

    cout << *it << "\n";

    return 0;
