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.
