How to find the minimum and maximum element of a Vector using STL in C++?

Given a vector, find the minimum and maximum element of this vector using STL in C++.

Example:

Input: {1, 45, 54, 71, 76, 12}
Output: min = 1, max = 76

Input: {10, 7, 5, 4, 6, 12}
Output: min = 1, max = 76

Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach:

• Min or Minimum element can be found with the help of *min_element() function provided in STL.
• Max or Maximum element can be found with the help of *max_element() function provided in STL.

Syntax:

*min_element (first_index, last_index);

*max_element (first_index, last_index);

Below is the implementation of the above approach:

 // C++ program to find the min and max element// of Vector using *min_element() in STL  #include using namespace std;  int main(){    // Get the vector    vector a = { 1, 45, 54, 71, 76, 12 };      // Print the vector    cout << "Vector: ";    for (int i = 0; i < a.size(); i++)        cout << a[i] << " ";    cout << endl;      // Find the min element    cout << "\nMin Element = "         << *min_element(a.begin(), a.end());      // Find the max element    cout << "\nMax Element = "         << *max_element(a.begin(), a.end());    return 0;}
Output:
Vector: 1 45 54 71 76 12

Min Element = 1
Max Element = 76
