查找大于平均值的数组元素

给定一个数字数组，请打印所有大于平均值的元素。

例子：

Input : 5, 4, 6, 9, 10
Output : 9 10
Explanation:
avg = 5 + 4 + 6 + 9 + 10 / 5;
avg = 34 / 5
avg = 6.8
Elements greater than 6.8 are 9 and
10

Input : 1, 2, 4, 0, 5
Output : 4 5

1)查找元素的平均值。
2)再次遍历数组并打印大于平均值的元素，

C++

// A C++ program to print elements which are
// greater than avg of array
#include 
using namespace std;
 
// Print array elements greater than average
void printAboveAvg(int arr[], int n)
{
    // Find average
    double avg = 0;
    for (int i = 0; i < n; i++)
        avg += arr[i];   
    avg = avg / n;
 
    // Print elements greater than average
    for (int i = 0; i < n; i++)
        if (arr[i] > avg)
            cout << arr[i] << " ";
}
 
// Driver program
int main()
{
    int arr[] = { 5, 4, 6, 9, 10 };
    int a = sizeof(arr) / sizeof(arr[0]);
    printAboveAvg(arr, a);
    return 0;
}

Java

// greater than avg of array

class GFG {
 
    // Print array elements greater than average
    static void printAboveAvg(int arr[], int n)
    {
         
        // Find average
        double avg = 0;
        for (int i = 0; i < n; i++)
            avg += arr[i];
        avg = avg / n;
     
        // Print elements greater than average
        for (int i = 0; i < n; i++)
            if (arr[i] > avg)
                System.out.print(arr[i] + " ");
    }
 
    // Driver program
    public static void main (String[] args)
    {
        int arr[] = { 5, 4, 6, 9, 10 };
        int a = arr.length;
        printAboveAvg(arr, a);
     
    }
}
