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
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
#include <bits/stdc++.h>
using namespace std;
int main()
{
vector<int> a = { 1, 45, 54, 71, 76, 12 };
cout << "Vector: ";
for (int i = 0; i < a.size(); i++)
cout << a[i] << " ";
cout << endl;
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)
