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 = 4, max = 12```

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)
