    This is my code in Python. Should be easy to understand even for beginners.

    lst = map(int,raw_input().strip().split(' '))
x = sum(lst)
print (x-(max(lst))), (x-(min(lst)))

    Hello friends,

    In this video tutorial, I have explained hackerrank mini-max sum solution algorithm. hackerrank mini-max sum problem can be solved by using one for loop. The complexity of mini-max sum hackerrank solution is O (n).

    If interested to know more about the generic algorithm in details-

    click here for the video explanation of generic algorithm with complexity analysis.

    or you can click on the image too to follow youtube tutorial.

    Here is the working solution:-

    source code :

    static void miniMaxSum(int[] arr) {
		long min = 0, max = 0, sum = 0;
		min = arr[0];
		max = min;
		sum = min;
		for (int i = 1; i < arr.length; i++) {
			sum += arr[i];
			if (arr[i] < min) {
				min = arr[i];
			}
			if (arr[i] > max) {
				max = arr[i];
			}
		}
		System.out.print((sum - max) + " " + (sum - min));

	}

    Would really appreciate your feedback like, dislike , comment etc. on my video.

    Java solution, in linear time. The idea is that always the max sum will be (totalSum - the min number) and min Sum will be (totalSum - maxNum) 

    public class Solution {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        long[] nums = new long[5];
        
        long max = 0, min= 0 , sum =0;
        nums[0] = max = min = sum = in.nextLong(); //Read the first value outside the loop, to handle min calculation
        for (int i = 1; i < 5; i++) {
            nums[i] = in.nextLong();
            if(nums[i]>max) max = nums[i];
            if(nums[i]<min) min = nums[i];
            sum += nums[i];
        }
        System.out.println( (sum - max) + " " + (sum - min));
       
    }
}

    Python is the best

    x = sum(arr)

minValue = x - max(arr)
maxValue = x - min(arr)

print(minValue, maxValue)

    My solution in c# :D

    string[] arr_temp = Console.ReadLine().Split(' ');
            long[] arr = Array.ConvertAll(arr_temp, Int64.Parse);
            long result1 = 0;
            long result2 = 0;
            long max = arr.Max();
            long min = arr.Min();
            for (int i = 0; i < arr.Length; i++)
            {
                result1 += arr[i];
                result2 += arr[i];
            }
            Console.WriteLine("{0} {1}",result1 - max,result2 - min);
