Program to Compute Average excluding Largest and Smallest Values
Program to Compute Average excluding Largest and Smallest Values
Description:
Given an array arr[] of integers, write a program to compute the average value of the array, excluding the largest and smallest values.
Input: arr = {2, 6, 4, 9, 1, 5}
Output: Average excluding largest and smallest values: 4
Explanation: The array is {2, 6, 4, 9, 1, 5}, and after excluding the largest value 9 and the smallest value 1, the remaining values are {2, 6, 4, 5}. The average of these values is (2 + 6 + 4 + 5) / 4 = 4.
Constraints:
The array length |arr| is at least 3 and at most 10^5. Elements in the array are integers ranging from -10^9 to 10^9.
Java Code:
import java.util.Arrays;
public class HackerAlgo {
// Compute Average excluding Largest and Smallest Values
public static double computeAverage(int[] arr) {
int n = arr.length;
if (n < 3) {
System.out.println("Array length should be at least 3 for computing average.");
return 0.0;
}
Arrays.sort(arr);
double sum = 0;
for (int i = 1; i< n - 1; i++) {
sum += arr[i];
}
return sum / (n - 2);
}
public static void main(String[] args) {

int[] arr = {2, 6, 4, 9, 1, 5};
double result = computeAverage(arr);
System.out.println("Average excluding largest and smallest values: " + resultPython Code:
