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
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 <bits/stdc++.h> 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)
