Java Solution Easy to understand public static void miniMaxSum(List arr) {

Collections.sort(arr);

long minSum = 0;
long maxSum =0;


for(int i = 0; i < arr.size() -1; i++ ){
    minSum += arr.get(i);
}

for(int i = 1; i < arr.size() ; i++ ){
    maxSum += arr.get(i);
}

System.out.println(minSum + " " + maxSum);
}
