Question
So this is a function that prints the two space-separated long integers denoting the respective minimum and maximum values that can be calculated by summing exactly four of the five integers. (The output can be greater than a 32 bit integer.) I want detailed explanation on the part of the code that is in bold and underlined in the starting of the function (long sum = *arr; int min = *arr; int max = *arr;). I cant understand the purpose and the logic behind this specific initialization.
Sample Input
1 2 3 4 5
Sample Output
10 14
The actual code-
void miniMaxSum(int arr_count, int* arr) {
long sum = *arr;
int min = *arr;
int max = *arr;
for(int i = 1; i < arr_count; i++){
sum = sum + arr[i];
if(arr[i] > max){
max = arr[i];
}
if(arr[i] < min){
min = arr[i];
}
}
printf("%ld %ld", sum - max, sum - min);
}
