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

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

```Input: {1, 45, 54, 71, 76, 12}
Output: 76

Input: {1, 7, 5, 4, 6, 12}
Output: 12```

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

Approach: Max or Maximum element can be found with the help of *max_element() function provided in STL.

Syntax:

`*max_element (first_index, last_index);`

## CPP

 `// C++ program to find the max``// of Array using *max_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 max element``    ``cout << "\nMax Element = "``         ``<< *max_element(a.begin(), a.end());``    ``return` `0;``}`

Output:

```Vector: 1 45 54 71 76 12

Max Element = 76```

Time Complexity: O(N), where N is number of elements in the given range of the vector.
Auxiliary Space: O(1)
