Vector min_element
Summary
Find the minimum element in a vector (or array) using the std::min_element algorithm provided by the Standard Template Library (STL). This problem requires understanding how to use STL algorithms effectively.
Detailed Explanation
The problem is straightforward: given a vector of integers, find the smallest element in it. We can achieve this using the std::min_element algorithm from the <algorithm> header file.
Here's a step-by-step breakdown:
- Include the necessary header files:
<vector>and<algorithm>. - Use
std::min_elementto find the minimum element in the vector. This algorithm returns an iterator pointing to the smallest element.
Here's a code example:
import java.util.Arrays;
public class Main {
public static void main(String[] args) {
int[] arr = {4, 2, 9, 6, 23, 12, 34, 0};
int minVal = Arrays.stream(arr).min().getAsInt();
System.out.println("Minimum element in the array is: " + minVal);
}
}
