# 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```

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:

## CPP

 `// 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<``int``> 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```

Time Complexity: O(N)
Auxiliary Space: O(1)
