Declare methods for calculating the sum average maximum and

Declare methods for calculating the sum, average, maximum, and minimum of the list. Their implementation should be straightforward.

I need help creating the methods to calculate the above. It is for a list in c#.

Solution

using System;
using System.Collections.Generic;
class MainClass {
public static void Main (string[] args) {
   List<int> numbers = new List<int>();
   numbers.Add(1);
   numbers.Add(2);
   numbers.Add(6);
    Console.WriteLine($\"Sum   :   {sum(numbers)}\");
    Console.WriteLine($\"Average   :   {average(numbers)}\");
    Console.WriteLine($\"Maximum   :   {maximum(numbers)}\");
    Console.WriteLine($\"Minimum   :   {minimum(numbers)}\");
}
/* add all the numbers and return sum */
public static int sum(List<int> numbers){
   int s = 0;
   foreach(int num in numbers){
       s += num;
   }
   return s;
}
/* find the sum of given numbers and divide by numbers Count */
public static double average(List<int> numbers){
   double s = sum(numbers);
   return s/numbers.Count;
}
/* Loop through the numbers and find the maximum */
public static int maximum(List<int> numbers){
   int max = numbers[0];
   for(int i=1;i<numbers.Count;i++){
       if(numbers[i]>max)
           max = numbers[i];
   }
   return max;
}
/* Loop through the numbers and find the minimum */
public static int minimum(List<int> numbers){
   int min = numbers[0];
   for(int i=1;i<numbers.Count;i++){
       if(numbers[i]<min)
           min = numbers[i];
   }
   return min;
}
}
