Given an array arr[], find the maximum element of this array 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 sort() in STL #include <bits/stdc++.h> using namespace std;
int main()
{ // Get the array
int arr[] = { 1, 45, 54, 71, 76, 12 };
// Compute the sizes
int n = sizeof (arr) / sizeof (arr[0]);
// Print the array
cout << "Array: " ;
for ( int i = 0; i < n; i++)
cout << arr[i] << " " ;
// Find the maximum element
cout << "\nMax Element = " << *max_element(arr, arr + n);
return 0;
} |
Output
Array: 1 45 54 71 76 12 Max Element = 76
Time Complexity:- O(n)
Auxiliary Space: O(1)
As constant extra space is used.
